Question

calculate the kinetic energy of a 3kg ball with velocity of 4m/s
48 j
48 j
52 j
24 j

Explanation:

Step1: Convert velocity unit

Velocity \(v = 6m/s\), mass \(m = 3kg\).

Step2: Use kinetic energy formula

The formula for kinetic energy is \(K.E=\frac{1}{2}mv^{2}\).
Substitute \(m = 3kg\) and \(v = 6m/s\) into the formula:
