Question

A body start up from rest and
acquires a velocity of Ams" in 5s.
Calculate
(a) the acceleration
(b) the distance covered in s
(c) the distance covered in 5th second.
(a) 1.6 ms. (b) 20 m, (c)72m​

Answer 1

Answer:

I think Ams is not correct

Explanation:

The body start from rest so u=0

velocity=v=12m/s

time=t=5s

v=u+at

12=0+a(5)

a=12/5=2.5m/s^2

s=ut+1/2(at^2)=1/2((2.5)(25)=31.25m
