Question

A rubber band with a mass of .003 kg is projected at a velocity of 22
m/s. What is the kinetic energy of the rubber band?

1 452 J
0.066 Ј
0.033 Ј
0.726 J

Answer 1

Kinetic Energy of the rubber band is 0.033 J

Explanation:

• Kinetic Energy is the energy that a particle or body possesses due to its motion.
• It is given by the formula KE = 1/2 mv²; Here, mass = 0.003 kg and velocity = 22 m/s

KE = 1/2 × 0.003 × 22

     = 11 × 0.003 = 0.033 J
