Question

A man starts his journey from rest and gains a velocity of 20m/s in 2s. Find its acceleration?

Answer 1

Answer:

ANSWER

At the moment when the car will be overtaking the truck their velocitis will be same.

so suppose after t second from the start of the motion the car overtake the truck then the velocity of the car at that moment will be v=0+at=t×1m/s

2

=t m/s

and the velocity of the truck at that moment will be u=6m/s(constant)

both should be same i.e u=v or 6=t or t=6 second

so the distance covered by truck oe car because both will be at same place ast that point of time in this time

will be s=vt=6×6=36meter. Please mark the answer as the branliest

Answer 2

Answer:

10 m/s^2

Explanation:

u=0 m/s

v= 20 m/s

t= 2s

a = v-u/t = 20 - 0/ 2 = 20/2 = 10m/s^2
