Ball 1 is launched with an initial vertical velocity v₁ = 161 ft/sec. Ball 2 is launched 3 seconds later with an initial vertical velocity v2. Determine v₂ if the balls are to collide at an altitude of 283 ft. At the instant of collision, is ball 1 ascending or descending? Answer: V₂ = ft/sec Note: The number of significant digits is set to 3. The tolerance is ±1 in the third significant digit.

At launch a rocket has a mass of 3.66×104 kg, and the thrust of the engines is 5.34×105 N. If the rocket is launched straight upwards from the surface of Earth, what is the initial acceleration of the rocket? Take upwards to be the positive direction. Express your answer in m/s2 to 3 significant figures. Use g=9.81 m/s2.

Consider two spherical raindrops. The first raindrop is small with radius R1, and the second is big with radius R, = 1.5 R1. As each raindrop falls through the atmosphere, it eventually reaches its terminal velocity. Suppose the terminal velocity of the first raindrop is vr1 = 8 m/s. Calculate the terminal velocity of the second raindrop.

A firecracker moves vertically upward and after reaching the highest point in its vertical trajectory, it starts falling down. After it falls down by 17.7 meters in air it cracks into two identical pieces. One of the pieces shoots off horizontally with 11.8 m/s speed. What would be the magnitude of the velocity of the other piece right after they split? Enter your answer in m/s. On your paper, show both your calculation for the magnitude and also the direction of the velocity vector of the second piece. Show your work in detail including your physics- based reasoning.

A child with mass of 16.5 kg stands on the edge of a park bench and leaps into the air. Her initial speed is 2.4 m/s directed at an angle of 30 degrees above the horizontal. After 0.28 seconds what is the horizontal component of her velocity in m/s?
A person throws a ball with speed 102 m/s at a 45° angle. How many seconds faster would the ball arrive if the person threw the ball at the same speed and the same distance but made the trip in two identical bumps. Assume that there is no loss of speed at the bounce. Hint: Use R = v2/g * sin(2θ) and t=2*vy(sinθ)/g.
A golf ball is hit from the ground (elevation is zero) and takes off with a launch speed of 55 m/s and a launch angle of 25 degrees. The acceleration due to gravity g = 9.81 m/s2 downward (negative y direction). The wind resistance is proportional to velocity and is defined by constant k = 0.014 N / (m/s). The mass of the golf ball m = 46 grams. 1) Determine the horizontal x1(t) and vertical y1(t) positions as a function of time ignoring air / wind resistance in both the x and y directions. 2) Determine the horizontal x2(t) and vertical y2(t) positions as a function of time including air / wind resistance in both the x and y directions. 3) For the case ignoring wind / air resistance, calculate how long the ball is in the air (in seconds) and how far away the ball lands from where it was hit (in meters).
