Question

A car starts with velocity 10 and accelerate 5 M per second square find the final velocity when the car has travelled a distance of 30 M

Answer 1

2as =v Square - u square
So, 2*5*30=v Square - 10 Square
300 = v Square - 100
300+100 = v Square
400 = v Square
Underroot 400 =v
20 = v

So the final velocity of the car is 20 m/sec

Answer 2

Hay mate here is ur ans
we know third equation of motion is
v square=u square+2as
v square=10x10+2x5x30
v square=100+300
v square=400
v= root 400
v=20m/s
