Question

a body starts moving from rest and acquire a speed of 4m/s in 20 sec. find its average acceleration​.

Answer 1

Answer:

First the Initial Velocity ( u ) is 0m/s

And Final Velocity ( v ) is 4 m/s

Time Taken is 20 seconds

To find its average acceleration -

formula is FINAL VELOCITY - INITIAL VELOCITY DIVIDED BY TIME TAKEN

$4 - 0 \div 20$

4-0/20

=4/20

=5

so average acceleration is 5m/s
