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

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.

The Kinetic energy possessed by the bowling ball while rolling is 14.52J.

Given the data in the question;

Mass of bowling ball; [tex]m = 7.26kg[/tex]

Speed of the bowling ball; [tex]v = 2m/s[/tex]

Kinetic energy; [tex]K_E =\ ?[/tex]

Kinetic energy is the energy that an matter or object has due to its motion.

It is expressed as:

[tex]K_E = \frac{1}{2} mv^2[/tex]

Where m is the mass and v is the velocity or speed.

We substitute our given values into the equation

[tex]K_E = \frac{1}{2} * 7.26kg \ *\ (2m/s)^2 \\\\K_E = 3.63kg \ *\ 4m^2/s^2\\\\K_E = 14.52 kg.m^2/s^2\\\\K_E = 14.52 J[/tex]

Therefore, the Kinetic energy possessed by the bowling ball while rolling is 14.52J.
