Question

he calculation of kinetic energy uses the formula, KE = 1 2 mv2. Identify the unit that is required for mass and velocity, respectively, to determine the kinetic energy in Joules.

Answer 1

Explanation:The kinetic energy of a moving object is given by:

where m is the mass of the object and v is its speed. The ball in this problem has a mass of m=0.5 kg and a velocity of v=10 m/s, therefore if we plug these numbers into the formula, we find the kinetic energy of the ball:

Answer 2

Mass is measured in kg
Velocity is measured in ms^-1
