Question

A golf ball with a mass of 0.05 kg travels down the fairway with a velocity of 60.0 m s . Calculate the kinetic energy of the golf ball.

Answer 1

90 J

Step-by-step explanation:

The kinetic energy of an object is given by:

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

where

m is the mass of the object

v is its speed

The ball in this problem has a mass of m=0.05 kg and a speed of v=60.0 m/s, therefore its kinetic energy is

`K=(1)/(2)mv^2=(1)/(2)(0.05 kg)(60.0 m/s)^2=90 J`
