Question

Kinetic energy is the energy of a moving object. The kinetic energy of an object can be found by using the following formula, where represents the mass of the object in kilograms and represents the velocity of the object in meters per second. What is the kinetic energy of a 42 kg mass traveling at 25 meters per second?

Answer 1

13125

Explanation:

The formula for kinetic energy is 1/2 times mass times velocity squared

in this situation the formual is 1/2 × 42 × 25 squared

42 divided by two is 21 so the new problem is

21 × 25 squared which is also

21 × 25 × 25= 13125 joules
