Question

1. a 1,200 kg car is moving at 20 m/s. what is its kinetic energy? 12,000 j 960,000 j 240,000 j 480,000 j

Explanation:

Step1: Recall the kinetic energy formula

The formula for kinetic energy is \( KE=\frac{1}{2}mv^{2} \), where \( m = 1200\space kg \) (mass of the car) and \( v = 20\space m/s \) (velocity of the car).

Step2: Substitute the values into the formula

Substitute \( m = 1200\) and \( v = 20 \) into \( KE=\frac{1}{2}mv^{2} \).
