018 10.0 points During a baseball game, a batter hits a high pop-up. If the ball remains in the air for 5.19 s, how high above the point where it hits the bat does it rise? Assume when it hits the ground it hits at exactly the level of the bat. The acceleration of gravity is 9.8 m/s. Answer in units of m. 019 10.0 points An engineer in a locomotive sees a car stuck on the track at a railroad crossing in front of the train. When the engineer first sees the car, the locomotive is 100 m from the crossing and its speed is 18 m/s. If the engineer's reaction time is 0.8 s. what should be the magnitude of the minimum de- celeration to avoid an accident? Answer in units of m/s 020 (part 1 of 3) 10.0 points A tennis ball is dropped from 1.72 m above the ground. It rebounds to a height of 0.869 m. With what velocity does it hit the ground?
