Answer:
For the first one its about 25 feet
Explanation:
Answer:
Maximum height, h = 10 m
Explanation:
It is given that,
Mass of golf ball, m = 45 g = 0.045 kg
The ball comes down on a tree root and bounces straight up with an initial speed of 14.0 m/s.
We need to find the height the ball will rise after the bounce. It is based on the conservation of energy such that,

h is maximum height raised by the ball

So, the ball will raised to a height of 10 meters.
Potential energy is high and kinetic is equal i believe.
