Question

What is the Kinetic Energy of a 478 kg object that is moving with a speed of 15 m/s?

Answer 1

Answer:

Kinetic Energy is 53.78 KJ

Explanation:

Step 1: Enumerate the given values.

Given:

m = 478 kg

v = 15 m/s

Step 2: Identify what is being asked.

Required:

Kinetic Energy

Step 3: Solve for Kinetic Energy

Solution:

The formula for Kinetic Energy is given by:

KE = ½ mv²

where:

KE - Kinetic Energy

m - mass  

v - velocity

Substituting the value of m and v in the formula,

KE = (½)(478 kg)(15 m/s)²

PE = 53,775 kgm²/s² or 53,775 or 53.78 KJ
