Question

Calvin rolls a bowling ball that weighs 3 kilograms, travels 5 meters, and moves at a speed of 10 meters per second. How much kinetic energy does the bowling ball have?

Answer 1

Hello friend,
Mass of the ball=3kg
Speed(velocity)of the ball = 10m/s
kinetic energy of the ball=1/2mv^2
=1/2*3*10^2
=1/2*3*100=3*50=150J
Hope it helps you dear

Answer 2

The kinetic energy of the bowling ball is 150 J.

Explanation:

Given that,

Mass of a ball, m = 3 kg

It travels a distance of 5 meters.

Speed of the ball, v = 10 m/s

The kinetic energy of the ball is given by :

$E=\dfrac{1}{2}mv^2\\\\E=\dfrac{1}{2}\times 3\times (10)^2\\\\E=150\ J$

So, the kinetic energy of the bowling ball is 150 J.
