Question

The bowling ball in the following figure is whizzing down the bowling lane at 4 m/s. If the mass of the bowling ball is 7 kg, what is its kinetic energy?

Answer 1

Answer:

Answer for this question is 3590792.

Answer 2

Answer:

56 Joules

Explanation:

We are given:

Mass of the Ball = 7 kg

Velocity of the Ball=  4 m/s

Kinetic Energy of the Ball:

We know that:

Kinetic Energy = 1/2 (Mass * Velocity²)

replacing the values

Kinetic Energy = 1/2(7 * (4)²)

Kinetic Energy = 1/2(7 * 16)

Kinetic Energy = 56 Joules
