Question

A bus starting from rest attains a velocity 72km.p.h. in 5 minutes.if the acceleration is uniform,it's acceleration is

Answer 1

Answer:

Explanation:

see, all we need to know is that

a = Δv/Δt = velocity by time

now, let's convert velocity to m/s = 72 * 1000/3600 = 20m/s

20/Δt = a

20/5 * 60 = a

2/30 = a

or 0.067m/s^2 = a

hope it helped, please mark as brainliest if it did

Answer 2

Answer:

given u=0 and v=(72×5)/18=20m/sec

a= (20-0)/5×60

a=20/300

a=0.066m/sec^2.
