Question

calculate the acceleration of a car if its velocity decreases from 54 kmph to 0 kmph in 3 seconds​

Answer 1

Hi,

Here is your answer

Given:

Initial velocity(u)=54km/hr=15m/s

Final velocity(v)=0km/hr=0m/s

Time taken(t)= 3s

To Find:

Acceleration(a)

Solution:

Acceleration is defined as change in velocity per unit time.

The equation for it is given as

a=(v-u)/t

Substitute the given datas in the equation

We get,

a=(0-15)/3

a= -5m/s

Here it is negative, because the car is undergoing deceleration.

Hope this helps you.
