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.

Neglecting air resistance, what will be its

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?
