Question

A man of mass of 90kg is moving at a constant
velocity. He has kinetic energy of 2205J.
Calculate his velocity.

Answer 1

Answer:

hello..

Explanation:

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
