Question

A bowling ball travels at 2.0 m/s. It has 16 J of kinetic energy. what Is the mass of the bowling ball in kilograms ?

Answer 1

kinetic energy = 1/2 × m × v^2
16 = 1/2 × m × 2^2
16 = 1/2 × m × 4
16 = 2 × m
16/2 = m
8 = m

so the mass is 8 kg

Answer 2

Given the velocity and kinetic energy the mass of the bowling ball, its mass is 8 kilograms.

What is Kinetic Energy?

Kinetic energy is simply a form of energy a particle or object possesses due to its motion.

It is expressed as;

K = (1/2)mv²

Where m is mass of the object and v is its velocity.

Given the data in the question;

• Velocity of the ball V = 2m/s

• Kinetic energy of the train K = 16J = 16kgm²/s²

• Mass of the train m = ?

K = (1/2)mv²

16kgm²/s² = (1/2) × m × (2m/s)²

16kgm²/s² = 0.5 × m × 4m²/s²

16kgm²/s² = m × 2m²/s²

m = 16kgm²/s² ÷ 2m²/s²

m = 8kg

Therefore, Given the velocity and kinetic energy the mass of the bowling ball, its mass is 8 kilograms.
