Question

A Martian rover is moving up a hill sloped at 30.0° with the horizontal. If it has a constant velocity of 1.50 meters/second, calculate its vertical displacement after 21.0 seconds.

Answer 1

We first calculate the vertical component of the velocity:
Vy = Vsin∅
Vy = 1.5sin(30)
Vy = 0.75 m/s

Displacement = velocity x time
Displacement = 0.75 x 21
Displacement = 15.75 meters

Answer 2

Answer:

C.

15.75 meters
