Question

A car starts with a velocity of 10 metre second and accelerates at rate of 5 metre sec find the final velocity a distance 30m

Answer 1

hi friend,


given u=10m/s

a=5m/s²

s=30m

let v be the final velocity ...


we know that


v²=u²+2as

v²=10²+2(5)(30)

v²=100+300

v²=400

v=±20m/s


I hope this will help u:)

Answer 2

Hey friend !

hi friend,


Initial velocity =  u=10 m/s

acceleration = a = 5 m/s²

distance  covered = s = 30 m

final velocity  = v

Equation of motion :-

v² = u² + 2 as

v² = 10² +2× 5 × 30

v² = 100 + 300

v² = 400

 v = 20 m/s
