Question

A car starts from rest. Its velocity becomes 20 m/s in 8 s. Find its acceleration?

Answer 1

Answer:

Explanation:

a=v-u/t

where

u=0m/s

v=20m/s

t=8s

a=20-0/8

a=20/8

a=2.5m/s^2

Answer 2

Hi,

Here is your answer

Given:

Initial velocity(u)=0m/s

Final velocity(v)=20m/s

Time taken(t)= 8s

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=(20-0)/8

a= 2.5m/s²

Hope this helps you.
