Question

A bike was being driven at 36km/ h after 2 minutes rider increase its speed and now it is being driven at 54km/h .what is acceleration that was used by rider

Answer 1

Hi,

Here is your answer

Given:

Initial velocity(u)=36km/hr=10m/s

Final velocity(v)=54km/hr=15m/s

Time taken(t)=2min=120s

To find:

Acceleration(a)

Solution:

Acceleration is given by the equation

a=(v-u)/t

Substituting the given datas, we get

a=(15-10)/120

a=0.04m/s²

Notes:

1. Remember to convert all the given datas to the SI units before calculating.

2. Acceleration is defined as the rate of change of velocity. It's uit is m/s²

Hope this helps you.
