Answer to Question #91279 in Mechanics | Relativity for John

Question

An object, s velocity is 4m/s and the mass is 60 kg. What is the object, s kinetic energy.

Answer 1

We can find the object's kinetic energy from the formula:

$$KE = \dfrac{1}{2} mv^2 = \dfrac{1}{2} \cdot 60 kg \cdot (4 \dfrac{m}{s})^2 = 480 J.$$

Answer:

$KE = 480 J.$
