Question

A body moving with a velocity is brought to rest in 8 seconds. calculate its initial velocity if the body was decelerated by 2m/s2

Answer 1

v=u+at
use this formula.
ans is 16 m/s

Answer 2

initial velocity u =?
final " v= 0
accelaration =2m/s2

time = 8sec

a = v_u/t

2 = 0_u/ 8

2×8 = u

16 =u

intitial velocity u = 16
