Question

A motorcycle together with its Rider with 150 kg how much work is needed to set its movement at 15 metre per second.​

Answer 1

W = 16875 J

Step-by-step explanation:

We have,

Mass of a motorcycle together with its rider is 150 kg

It is required to find the work is needed to set its movement at 15 metre per second. The work done is given by :

`W=(1)/(2)mv^2`

Plugging all the values in above formula such that :

`W=(1)/(2)* 150* (15)^2\\\\W=16875\ J`

So, the work of 16875 J is needed.
