Question

a body is moving with a velocty of 12m/s and it comes to rest in 2 minutes, what is teh acceleration

Answer 1

Answer:

u= 12 v=0 t=2m=120s

v= u+at

12 + 120a = 0

120a = -12

a= -12/120 = -0.1 m/s^2

Answer 2

Answer:

Explanation:

Initial velocity= 12m/sec

Final velocity=. 0m/sec

Time= 2 min= 2*60sec

=120sec

Acceleration= (0-12)/120

=. -0.1m/sec^2
