How much more kinetic energy does a 6-kilogram bowling ball have when it is rolling at 16 mph (7.1 meters per second) than when it is rolling at 14 mph (6.2 meters per second)?

Use the formula: [tex] KE = \frac{1}{2}mv^2 [/tex]

A. 266.5 J
B. 13 J
C. 35.9 J
D. 151.2 J

Answer :

Answer:

Explanation:266.5jjjj

The kinetic energy of the bowling ball is 115.32 J.

What is kinetic energy?

Kinetic energy is the energy of a moving body.

To calculate the kinetic energy of the bowling ball, we use the formula below

Formula:

  • K.E = mv²/2.........................Equation 1

Where:

  • K.E = Kinetic energy
  • m = Mass of the bowling ball
  • v = Velocity

From the question,

Given:

  • m = 6 kg
  • v = 6.2 m/s

Substitute these values into equation 1

  • K.E = 6×6.2²/2
  • K.E = 115.32 J
