Question

A person hits a 45-g golf ball. The ball comes down on a tree root and bounces

straight up with an initial speed of 14.0 m/s. Determine the height the ball will rise
after the bounce. I really need help with this i jut cant solve it

Answer 1

Maximum height, h = 10 m

Step-by-step 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,

`(1)/(2)mv^2=mgh`

h is maximum height raised by the ball

`h=(v^2)/(2g)\\\\h=((14)^2)/(2* 9.8)\\\\h=10\ m`

So, the ball will raised to a height of 10 meters.
