Question

8. A body is moving with a velocity of 12m/s and it comes to rest in 18m, what was the acceleration?

Answer 1

u=12m/s
v=0m/s
s=18m
t=5 sec
v-u/t=a

a=0.11

Answer 2

Initial velocity (u) = 12m/s

Final velocity (v) = 0m/s

Time taken(t) = 18m = 18×60 seconds = 1080 seconds

As , we know formula of Acceleration →

(v-u)/t = (0-12)/1080

= -12/1080 m/s²

= -0.11 m/s²

Answer→ Acceleration of body is -0.11 m/s²
