Assume: A 78 g basketball is launched at an
angle of 56◦
and a distance of 17.9 m from the
basketball goal. The ball is released at the
same height (ten feet) as the basketball goal’s
height.
A basketball player tries to make a long
jump-shot as described above.
The acceleration of gravity is 9.8 m/s
2
.
What speed must the player give the ball?
Answer in units of m/s.
Look at the football problem below this one.
Note the mass has nothing to do with it.
Since it starts and finishes at the same height, the ten feet is also irrelevant.
