Question

A body is moving from rest at acceleration with4 m Per sec .find It s velocity after 4 second

Answer 1

Answer:

u = 0

a = 4m/s^2

t = 4 sec

v=?

PROCEDURE:-

Using 1st kinetic equation ;

v = u + a*t

v = 0 + 4*4

v = 16m/s

Answer 2

Answer:

16meter per second

Explanation:

so here the acceleration is constant

so we use the formula of velocity acceleration relation

that is
