Question

2. What is the kinetic energy of a 7.26 kg bowling ball that is rolling at a speed of 2 m/s?

Answer 1

The kinetic energy of bowling ball is 14.52J

Step-by-step explanation:

Given that the formula of kinetic energy is (1/2)mv². Then substitute the following value into the formula:

m = 7.26kg

v = 2m/s

k.e = (1/2)×7.26×2²

= 14.52J

Answer 2

Kinetic energy is the energy possessed by an object when that object is moving in space. The higher the mass of an object or higher the speed of an object the higher the kinetic energy will be.

So to calculate the Kinetic Energy we can use the following formula

K.E=(1/2)*m*v^2

Inserting the values in formula gives:

K.E=1/2*7.26*2^2

14.52J

This is the final answer which gives the kinetic energy of the ball.
