Question

A 712 kg car is traveling at 5.6 m/s when a force acts on it for 8.4s, changing its velocity to 10.2 m/s. What is the change in kinetic energy?​

Answer 1

Answer:

11164.16J    

Explanation:

Kinetic energy of the car is given by

KE = $\frac{1}{2} mv^{2}$

∴ KE = $\frac{1}{2}$ × 712 × (5.6)²

= 11164.16J

=11164.16J is correct answer
