Question

An object has a kinetic energy of 25 J and a mass of 34 kg. How fast is the object moving?

Answer 1

Kinetic energy is the energy possessed by an object with mass when in motion. It is calculates by 1/2 the product of the mass of the object and the square of its velocity.

KE = 1/2 (mv^2)
25 = 1/2 (34)(v^2)
v = 1.21 m/s
