A man leaps to his death from atop a 100-meter tall building. If his initial velocity is 5 m/s upward, determine

(a) the time of fall (the total time he spends in the air),
(b) the maximum height that the man reaches above the ground, (c) the velocity of the man just prior to impact and death.

A man throws a ball straight upward with speed 30 m/s from the top of a building that is 75 m high. Ignore air resistance and choose the vertical y-axis to be positive downward with origin at the point of throw (top of the building). Represent the initial velocity and the acceleration vectors in the reference y-axis above. Find the maximum height the ball reaches with respect to the ground. How long does it take the ball to reach the...

A model rocket is fired straight up from the top of a 55-m-tall building. The rocket has only enough fuel to burn for 3.0 s. But while the rocket engine is burning fuel, it produces an upward acceleration of 60 m/s2. After the fuel supply is exhausted, the rocket is in free fall and just misses the edge of the building as it falls back to the ground. Ignoring air resistance, calculate 1. Determine the height above the ground of...
