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
