A stone (on the edge of the roof) thrown from the top of
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
(a) The time at which the stone reaches its maximum
(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.
