Solutions

Expert Solution

Initially the car is at rest, the initial speed of the car is u=0

Final speed of the car is

Using 1 mile = 1609 meters and 1 hour = 3600 seconds

Time taken is t=2.4 seconds

The average acceleration of the car is

The average force required to accelerate the car at this acceleration is

Multiplying and dividing by g (gravitational acceleration on Earth)

Weight of an object of mass m is W=mg

Using W=3479lb, g=9.81m/s² we get

Assuming acceleration of the vehicle is constant, the motion of the vehicle is governed by the kinematics equation for uniformly accelerated motion, to find distance traveled we use
