Question

A 16-kg scooter is moving at a speed of 7 m/s. The scooters speed doubles.

What is the scooter's kinetic energy when its speed doubles?

Answer 1

\(\rm\huge K.E= \frac{1}{2}\cdot m\cdot v^2\)

Answer 2

if velocity doubles \[\rm K.E=\frac{1}{2}\cdot m\cdot (2v)^2 \\ ~= \frac{4}{2}\cdot m\cdot (v)^2~\\~ =4(\frac{1}{2}\cdot m\cdot (v)^2)\]
