Question

A 3.5kg bowling ball rolls down the alley at 8m/s. Calculate the kinetic energy that it hits the pins with how many jules

Answer 1

Answer:

112 J

Explanation:

The kinetic energy of a body is given as:

$KE = \frac{1}{2}mv^2$

where m = mass

v = velocity

The mass of the ball is 3.5 kg.

The velocity of the ball is 8 m/s.

The kinetic energy of the ball is therefore:

$KE = \frac{1}{2} * 3.5 * 8^2\\ \\KE = 112 J$
