Question #16641

1. A basketball player achieves a hang time of
1.11 s in dunking the ball.
What vertical height will he attain? The
acceleration of gravity is 9.8 m/s^2.
Answer in units of m
2. A bullet is ﬁred straight up from a gun with a
muzzle velocity of 263 m/s.

displacement after 7.8 s? The acceleration of
gravity is 9.8 m/s^2.
Answer in units of m
3. A rock is thrown downward from an unknown
height above the ground with an initial speed
of 30 m/s. It strikes the ground 8.7 s later.
Determine the initial height of the rock
above the ground. The acceleration of gravity
is 9.8 m/s^2
Answer in units of m
4. A ball is thrown straight up and passes point
B (at a height of 53.4 m above its starting
point O) in 4.6 s. What was its initial speed?
The acceleration of gravity is 9.8 m/s^2.
Answer in units of m/s
