Question

An object start fromrest and accelerates with 2m/s^2. what will be it's final velocity after 4 second.

Answer 1

AT REST THE INITIAL VELOCITY OF THE BODY IS GOING TO BE ZERO

U=0M/S

A=2M/S^2

T=4S

V=?

WE KNOW THAT V EQUALS INITIAL VELOCITY PLUS PRODUCT OF ACCELERATION AND TIME

V=U+AT

V=0+2*2

V=4M/S
