Question

A race car traveling at 12 m/s is uniformly accelerated to a velocity of 100 m/s over a

30 second interval. What is its acceleration during this time?
(Please provide your answer to 2 decimal places)

Answer 1

using the formula -- V=u+at

u=12m/s, v=100m/s, t=30s, a=?

100=12+a(30)

100-12=a(30)

88=a(30)

88/30=a(30)/30

2.93=a

a=2.93m/s²
