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

Respuesta :

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,

[tex]\dfrac{1}{2}mv^2=mgh[/tex]

h is maximum height raised by the ball

[tex]h=\dfrac{v^2}{2g}\\\\h=\dfrac{(14)^2}{2\times 9.8}\\\\h=10\ m[/tex]

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