Daniel takes his two dogs, Pauli the Pointer and Newton the Newfoundland, out to a field and lets them loose to exercise. Both dogs sprint away in different directions while Daniel stands still. From Daniel's point of view, Newton runs due North at 3.90m/s, but from Pauli's point of view, Newton appears to be moving at 1.50 m/s due East. What must Pauli's velocity relative to Daniel be for this to be true? Express your answer in terms of the ? and ?‑components if North is the +? direction and East is the +? direction. a) ?-component (m/s): ?-component (m/s): b) Express your answer as a magnitude and an angle measured counter‑clockwise from due East.

Daniel takes his two dogs, Pauli the Pointer and Newton the Newfoundland, out to a field and lets them loose to exercise. Both dogs sprint away in different directions while Daniel stands still. From Daniel's point of view, Newton runs due North at 4.65 m/s, but from Pauli's point of view, Newton appears to be moving at 2.10 m/s due East. What must Pauli's velocity relative to Daniel be for this to be true? Express your answer in terms of the x- and y-components if North is the +y-direction and East is the +x-direction. x-component: m/s Y-component: m/s Express your answer as a magnitude and an angle measured counter-clockwise from due East. magnitude & direction: at a angle counter-clockwise from due East
Bob has just finished climbing a sheer cliff above a level beach and wants to figure out how high he climbed. All he has to use is baseball, a stopwatch, and friend on the ground below with a long measuring tape. Bob is a pitcher and knows that the fastest he can throw the ball is about v_0= 34 m/s. Bob starts the stopwatch as he throws the ball, with no way to measure the ball’s initial trajectory, and he watches carefully. The ball rises and then falls, and after t_1= 0.510 s the ball is once again level with Bob. Bob cannot see we’ll enough to time when the ball hits the ground. Bob’s friend the measures that the ball hit the ground x= 127 m from the base of the cliff. How high above the beach was the ball when it was thrown? A projectile is launched from ground level with an initial speed of 45.5 m/s at an angle of 32.3 degrees above the horizontal. It strikes a target in the air 1.83 s later. What is the horizontal distance from where the projectile was launched to where it hits…
Two roads cross at right angles. An observer stands on the road 50 meters south of the intersection and watches an eastbound car traveling at 45 meters per second. At how many meters per second is the car moving away from the observer 5 seconds after it passes through the intersection?
Two children, one at the front of a parade float and one at the back, are playing catch with a ball. Each sees the other as tossing the ball at 4.0 m/s. The float moves down the road at 2.0 m/s. At what speed do the two children toss the ball from the point of view of a spectator watching the float move by?
. You are running north at 4.56ms. Another jogger is jogging north at 2.64ms. From your frame of reference, what is the speed and direction of the other jogger? speed of the other jogger in your frame of reference = ms*Round to the nearest hundredth if necessary. Don’t forget that north is in the positive direction and south is in the negative direction.
While standing at the second floor balcony in an apartment building at 3 meters above the ground, Peter throws a tennis ball upward to Tom, who is standing at the seventh floor balcony at 12 meters above the ground. The velocity with which Peter throws the ball is equal to 17 m/s. Tom successfully catches the ball while it is still moving upward. What is the velocity magnitude of the ball when Tom catches it?
Paul is standing outside the Physics laboratory 7 meters from the wall. Peter, by a window 5 meters above the ground, tosses a ball horizontally. Find the speed that Peter should give the ball for it to reach Paul.
Two cars approach a street corner at right angles to each other. One is red and one is blue. Both cars have the same speed of 40 km/hr. The blue car is moving due south and the red car is moving east. What is the velocity of the red car as seen by the observer in the blue car (find both the magnitude and the direction)?
Three cars, A,B, and C, are moving along a straight section of highway. If the velocity of A relative to B is +60m/s and the velocity of A relative to C is +20m/s, then what is the velocity of C relative to B?
Huck Finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion relative to the shore). The raft is traveling down the Mississippi River at a speed of 1.75 m/s relative to the river bank. What is Huck's velocity (speed and direction) relative to the river bank?
A laptop is projected horizontally from the rooftop of a condominium 138 m high. The laptop hits the ground at a point 49 m horizontally away from and below the point of release. What is the speed of the laptop just before it strikes the ground? Use g=9.8 m/s2 . Round off answer up to two decimal places. Include units (abbreviation only).
An athlete crosses a 28 meters wide river by swimming perpendicular to the water current at a speed of 1.1 m/s relative to the water. He reaches the opposite side at a distance of 42 meters downstream from his starting point. w = 28md = 42m vs = 1.1m/s How fast is the water in the river flowing with respect to the ground in m/s?
