You drop a ball from a window on an upper floor of a building and ii is caught by a friend on the ground when the ball is moving with speed vf. You now repeat the drop, but you have a friend on the street below throw another ball upward at speed vf exactly at the same time that you drop your ball from the window. The two balls are initially separated by 28.7 m. (a) At what time do they pass each other? (b) At what location do they pass each other relative the window?
Near the end of a marathon race, the first two runners are separated by a distance of 45.0 m. The front runner has a velocity of 3.50 m/s, and the second a velocity of 4.20 m/s. (a) What is the velocity of the second runner relative to the first? (b) If the front runner is 250 m from the finish line, who will win the race, assuming they run at constant velocity? (c) What distance ahead will the winner be when she crosses the finish line?

(b) If the bird turns around and flies with the wind, how long will he take to return 6.00 km? (c) Discuss how the wind affects the total round-trip time compared to what it would be with no wind.
Two hockey players are skating towards each other. They are 50.0 m apart. The first is accelerating from rest at 0.74 m/s2 and the second has already attained his maximum speed of 6.2 m/s. Find a) How long before they hit each other. b) How fast was the accelerating player going at the time of contact. c) How far has each player skated.
A footballer kicks a ball directly towards a wall 10m away and walks after the ball in the same direction at a constant speed 2m/s. The ball starts at 4m/s, but decelerates at a constant rate of 0.5m/s^2. When it hits the wall it rebounds to travel away from the wall at the same speed with which it hit the wall. a) Find the time after initial kick when the ball returns to the footballer. b) what assumptions have been made in your answer?
