What is the kinetic energy of a 24-kg mass that is moving with a velocity of 2 m/s?

48 J

Explanation:

Kinetic energy can be found using the following formula:

where m is the mass in kilograms and v is the velocity in m/s.

We know the mass is 24 kilograms and the velocity is 2 m/s Therefore, substitute 24 in for m and 2 in for v.

Evaluate the exponent first. 2^2 is the same as multiply 2, 2 times.

2^2=2*2=4

Multiply 24 and 4

Multiply 96 and 1/2, or divide 96 by 2.

Add appropriate units. Kinetic energy uses Joules, or J

The kinetic energy is 48 Joules

e/c, where e is its total energy

this would be about 43%
