Question

A car traveling at a speed of 18m/s loses its brake and falls into a 60-m cliff. Fill in the unknown quantities.

Initial velocity

Time for the car to hit the ground

How far from the foot of the cliff will the car reach?

Answer 1

Step-by-step explanation:

Initial velocity is 18 m/s horizontal.

Time for the car to hit the ground.

t = √(2h/g) = √(2(60) / 9.8) = 3.5 s

The car will land 3.5(18) = 63 m from the base of the cliff.
