Question

20.a body is moving with a velocity of 8m/s uniformly accelerated at 3.5m/s. what will be its velocity after 10 seconds and how far it will move during this time?

Answer 1

Explanation:

We know that

V=U +at

V=8+3.5×10

V=8+35

V=43 m/s

For finding the distance we can use both

S=ut+1/2at^2

Or

V^2-U^2=2as

I am using the first one

S=8×10+1/2×3.5×10×10

S=80+175

S=255m
