Question

If a Ferrari, with an initial velocity of 20 m/s, accelerates at a rate of 50 m/s/s for 3
seconds, what will its final velocity be?

Answer 1

Explanation:

tanα=acceleration

tanα=50m s2

vi=initial velocity

vf=final velocity

use defination of acceleration

a:acceleration

a=vf−vi Δt=tanα

50=vf−10 3

150=vf−10

vf=160m s

vf=150+10
