You leave your house, driving your car at a constant speed of 30 mph in a direction 20 degrees west of north for 2 hours. Then, you reach an intersection, make a 90 degree turn to the left. You then continue in that direction at a constant speed of 50 mph for one hour. Finally, you drive your car directly back to your house in a straight line path. How far do you travel during the return trip to your house? Give your answer to 3 sig ﬁgs.

A hiker walks 3.00 km north and then 4.00 km west, all in one hour and forty minutes, (a) Calculate his average speed in km/h. (b) Calculate the magnitude of his average velocity. (See Section 3.2 and 3.3.)
Acceleration a has the dimensions of length per time squared, speed v has the dimensions of length per time, and radius r has the dimension of length. Which of the following expressions may be correct? Explain your answer in each case. a. a = vr b. a = v/r c. a = v2/r d. a = v/r2
1. A pilot in a small plane encounters shifting winds. He flies 26.0 kmkm northeast, then 45.0 kmkm due north. From this point, he flies an additional distance in an unknown direction, only to find himself at a small airstrip that his map shows to be 70.0 kmkm directly north of his starting point. What was the length of the third leg of his trip? What was the direction of the third leg of his trip? 2. A boat can travel 7.3 m/s in still water. It is crossing a 220 m wide river while pointed due east and the river is flowing at 3.7 m/s, north. What is the speed of the boat, relative to the shore? How long does it take to cross the river? How far downstream does the boat end up? 3. A flock of ducks is trying to migrate south for the winter, but they keep being blown off course by a wind blowing from the west at 14 m/sm/s . A wise elder duck finally realizes that the solution is to fly at an angle to the wind. If the ducks can fly at 15 m/sm/s relative to the…
1. You drive 7.50 km in a straight line in a direction 15° east of north. (a) Find the distances you would have to drive straight east and then straight north to arrive at the same point. (This determination is equivalent to find the components of the displacement along the east and north directions.) (b) Show that you still arrive at the same point if the east and north legs are reversed in order.
A red cross helicopter takes off from headquarters and flies 75 km at 40 degrees south of west. There it drops off some relief supplies, then flies 90 km at 15 degrees west of north to pick up three medics. How far West is the helicopter from its starting point? km How far North is the helicopter from its starting point? km (Make this number negative if it is South of the starting point) For the helicopter to return home, how far would it need to fly, and in what direction?

What is her total displacement? 3. A body is moving at a uniform speed travels a distance of 120 m/s in 10 s. Find its average speed.
1. A pilot flies in a straight path for 1 h 30 min. She then makes a course correction, heading 10 degrees to the right of her original course, and flies 2 h in the new direction. If she maintains a constant speed of 610 mi/h, how far is she from her starting position?Your answer is mi;Enter your answer rounded to two decimal places. 2. A steep mountain is inclined 74 degree to the horizontal and rises to a height of 3400 ft above the surrounding plain. A cable car is to be installed running to the top of the mountain from a point 880 ft out in the plain from the base of the mountain. Find the shortest length of cable needed.Your answer is ft
1) A man flies a small airplane from Fargo to Bismarck, North Dakota—a distance of 180 mi. Because he is flying into a head wind, the trip takes him 2 h. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 h 15 min. What is his speed in still air, and how fast is the wind blowing? a. what is the speed (mph) in still air? b. wind speed (mph)? 2)A boat on a river travels downstream between two points, 60 mi apart, in 1 h. The return trip against the current takes 2 1/2 hours. a. What is the boat's speed (in still water)? b. How fast does the current river flow?
