Question

A cyclist and bike have a total mass of 105kg and a speed of 12m/s. Calculate the kinetic energy.

Answer 1

7560J

Step-by-step explanation:

Given parameters:

Mass of cyclist and bike = 105kg

Speed = 12m/s

Unknown:

Kinetic energy = ?

Solution:

The kinetic energy of a body is the energy due to the motion of a body.

It is mathematically expressed as;

K.E =
`(1)/(2)` m v²

Insert the parameters:

K.E =
`(1)/(2)` x 105 x 12² = 7560J
