Acar drives horizontally off a 83-m-high cliff at a speed of 25 m/s . ignore air resistance. part a how long will it take the car to hit the ground? how long will it take the car to hit the ground?

a.4.9 s
b.4.5 s
c.4.1 s
d.2.7 s
e.5.7 s

c. 4.1 s

Step-by-step explanation:

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.

Solve for t:

Switch sides:

Take positive square root:

In our given situation . We know .

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