We have been given that a car drives horizontally off a 83-m-high cliff at a speed of 25 m/s . Ignore air resistance.To solve our given problem, we will use free fall formula. The free fall formula states that the distance the object falls, or height, h, is 1/2 gravity times the square of the time falling.

Therefore, it will take 4.1 seconds the car to hit the ground and option 'c' is the correct choice.
