Question

A vehicle started from rest and attained a speed of 36 km/h in 5 minutes. Find the acceleration of the body

Answer 1

Answer:

a=0.033 m/s²

Explanation:

v = u+at

u=0 ( as it is at initially)

v = at

a= v/t

v = 36 km/h = 10 m/s ( 1 km/ h = 5/18 m/s)

t= 5 min = 5x60 sec=300 sec ( 1 min = 60 s)

a= v/t= 10/300 = 1/30 = 0.033 m/s²
