The "street" automobile with the greatest acceleration is the Tempest. It has an acceleration of 6.89 m/s2. Suppose the car accelerates from rest to a final speed of 96.5 km/h. How long does it take the Tempest to reach this speed?

The time taken by tempest is 3.889 seconds

We are required to find the time taken by tempest to reach the speed of 96.5 km/hour

The other quantities are in the unit of m/s and hence we must convert this speed into m/s

To convert any speed from km/hr to m/s we must multiply it with 5/18

Therefore, 96.5km/hr =96.5 x 5/18 =26.80 m/s

Using the formulas of motion in one dimension as the car is travelling in a single dimension,

acceleration a= 6.89 m/s^2

u=initial speed = 0

Applying the formula v=u+at, we get:

26.80 = 0+6.89 x t

t= 26.80/6.89

t= 3.889 seconds

Hence the time taken is 3.889 seconds
