a building is given an initial velocity of 20.0 m/s straight

upward. The building is 50.0 m high, as shown in Fig. 4.

Using tA = 0 as the time the stone leaves the thrower’s

hand at position ○A . The gravitational acceleration is 9.8

m/s

2

. Determine:

(a) The time at which the stone reaches its maximum

height;

(b) The maximum height;

(c) The time at which the stone returns to the height

from which it was thrown;

(d) The velocity of the stone at which the stone returns

to the height from which it was thrown;

(e) The velocity and position of the stone at t = 5.00s.
