Question

A 10-kilogram bicycle is traveling at a speed of 2m/s. what is the bike's kinetice energy?

Answer 1

The kinetic energy of an object of mass m moving with speed v is given by:

`K= (1)/(2)mv^2`
For the bicycle in our problem,
`m=10 kg` and
`v=2 m/s`, so the kinetic energy is

`K= (1)/(2)(10 kg)(2 m/s)^2=20 J`
