A coin is dropped from a hot-air balloon that is 280 m above the ground and rising at 8.5 m/s upward. For this problem use a coordinate system in which up is positive.
h = 280 m
v = 8.5 m/s
part(a):Find the maximum height reached for the coin in meters.
part(b): Find its position 4.00 s after being released in m.
part(c):Find its velocity 4.00 s after being released m/s.
part(d):Find the time before it hits the ground in seconds.
