1. A race car accelerates at a rate of 15.6 m/s. If it starts from rest, how much time till it
is traveling at 325 km/h?

Answer: 5.79 s

Explanation:

Vs=0 m/s starting speed(from rest)

Vf=325 km/h= 325*1000/3600= 90.28 m/s

a=15.6m/s²

Using equation for acceleration  we can find out time :

a=(Vf-Vs)/t

t=(Vf-Vs)/a

t=(90.28 m/s-0m/s)/15.6 m/s²

t=5.79 s
