Question

A body moving with uniform acceleration describes 12m in third second of its motion and 20 m in v second find the velocity after 10 8 second

Answer 1

$\huge\red{Answer }$

As the body is in unform acceleration then the body

velocity per second

4m. 1

8m. 2

12m. 3

16m. 4

20m. 5

it will get increased by 4m per second

then (4 metres x 10 second)

= 40 m

therefore the velocity of body is 40m after 10 seconds
