A nasty teenager is throwing tomatoes off a bridge at cars on the road below. The height of the bridge is 10 m above the ground. The teenager first sees the cars when they come around a corner 50 m distance. All the cars are driving exactly at the speed limit of 40 kilometers per hour. Considering g = 10 m/s2 (a) how long after a car goes around the corner must it wait before it drops a tomato to hit the hood of the car at a height of 1.0 m above the ground? (b) After a while, the teenager gets bored just dropping the tomatoes. As a challenge, he decides to throw the tomatoes upward with an initial velocity, v0, instead of just dropping them. Suppose he drops the balls 1.5 s after seeing the cars, what value of v0 is needed for the balls to hit the cars? (c) Eventually, the teenager gets bored with this new game and decides to throw the balls downward at an initial velocity of 15 m/s. Now, how long must he wait after he sees the cars to hit them?
