Question

An object of mass m = 5 Kg is moving with a speed V = 2m/s Find the K.E of the moving body

Answer 1

10 joules

Step-by-step explanation:

formula for kinetic energy= 1/2mv²

mass (m) given = 5kg

velocity (v) given = 2m/s

therefore, by inputting them into the formula

= 1/2(5)(2)²

= 1/2 x 5 x 2²

= 1/2 x 5 x 4

= 1/2 x 20

= 10J
