Question

3. A scooter acquires a velocity of 36km/h in 10 seconds just after the start. Calculate the

acceleration of the scoter. ​

Answer 1

Hi,

Here is your answer

Given:

Initial velocity(u)=0m/s

Final velocity(v)=36km/hr=10m/s

Time=10s

To Find:

Acceleration(a)

Solution:

Acceleration is given by the equation

a=(v-u)/t

Substitute the given datas

We get

a=(10-0)/10

a=1m/s²

Notes:

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

2.Acceleration is the rate of change of velocity. It's unit is m/s²

Hope this helps you.

Answer 2

Initial velocity is 0 since the scooter has started. Final velocity is equal to 36kmph which is equal to 10 m/s. Time is 10 sec. the acceleration is the rate of change in velocity. Hence, it will be v-u/t and is 10-0/10 which is equal to 1 m/s^2
