Question

A car has an initial velocity of 10m/s. It accelerates at a rate of 2m/s2 until it reaches 30m/s. How far does it travel and for how long?

Answer 1

Answer:

acceleration=(v final-vinitial)/time

a=(vf-vi)/t

2=(30-10)/t

2=20/t

t=20/2=10 seconds

distance=v0t+at²/2

d=10 x 10+ 2x 10²/2=100+100= 200 m
