Question

a toy car of mass 2.75 kg moves forward at a speed of 1.00 m/s. which is the cars kinetic energy from this forward motion?
7.56 j
2.75 j
1.38 j
3.78 j

Explanation:

Step1: Recall the formula for kinetic energy

The formula for kinetic energy is \(K = \frac{1}{2}mv^{2}\), where \(m\) is the mass and \(v\) is the velocity.

Step2: Substitute the given values into the formula

Given \(m = 2.75\space kg\) and \(v = 1.00\space m/s\).
