a race car can be driven to a maximum speed of 33m/s. suppose the driver started at rest and underwent a constant acceleration with a magnitude of 3.0m/s^2. what distance would he have had to travel in order to reach the maximum speed?
a-0.006 m
b-125 m
c-181.5 m
d-5.5 m

Step by step answer:

Use this formula: [tex]v^{2}-v_{0}^{2} = 2aS[/tex]

Maximum speed: [tex]v = 33 m/s[/tex]

Started at rest: [tex]v_{0}=0[/tex]

Constant acceleration: [tex]a = 3.0 m/s^{2}[/tex]

So we can calculate [tex]S = \frac{33^{2}-0^{2} }{(2)(3.0)} =181.5m[/tex].
