Question #34513

a travels from rest with acceleration 8 metre per second square.Find its velocity when it has covered a distance of 100metre

Expert's answer

S = (V^2 - Vo^2)/2a

Where a - acceleration

Vo - velocity in the start = 0 m/s

V - velocity in the end

S = 100 m - distance

So,

V = sqrt(2as) = sqrt(2*8*100) = 40 (m/s)

Where a - acceleration

Vo - velocity in the start = 0 m/s

V - velocity in the end

S = 100 m - distance

So,

V = sqrt(2as) = sqrt(2*8*100) = 40 (m/s)
