in the movie thelma and louise, the two actresses drove off a cliff at the end. in preparation for the scene, their stunt doubles determined that the cliff was 50.0 m high. the director wants the car to land 90.0 m from the base of the cliff close to the camera location. how fast must the car be traveling in order to land at this location?



Answer :

The car must be travelling at a speed of 28.21 m / s in order to land 90 m from the base of a 50 m high cliff.

According to Equations of motion,

s = ut + 1 / 2 at²

s = Distance

u = Initial velocity

t = Time

a = Acceleration

In vertical motion,

s = 50 m

u = 0

a = 9.8 m / s²

50 = 0 + 1 / 2 * 9.8 * t²

t² = 50 / 4.9

t² = 10.2

t = 3.19 s

In horizontal motion,

s = 90 m

a = 0

90 = 3.19 u + 0

u = 90 / 3.19

u = 28.21 m / s

Therefore, the initial speed of the car must be 28.21 m / s
