A ball is thrown upward from the top of a 24 m tall building. The ball’s initial speed is12 m/s. At the instant, a person is running on the ground at a distance of 31 m fromthe building. What must be the average speed of the person if he is to catch the ballat the bottom of the building?

6. Lebron throw an apple vertically upward from the roof of a tall building. The apple leaves his hand at a point even with the roof railing with an upward speed of 15.0 m/s; the apple is then in free fall. (Ignore air resistance.) On its way back down, it just misses the railing. Find (a) the apple's position and velocity 1.00 s and 4.00 s after leaving his hand; (b) the apple's velocity when it is 5.00 m above the railing; (c) the maximum height reached.
