Question

A box is sitting stationary on a ramp that is 42° to the horizontal. The box has a gravitational force of 112.1 N. What is the minimum amount of force that can be applied to the box to get the box to move?

Answer 1

Answer is 80

Step-by-step explanation:

I just took the tets

Answer 2

Force of gravity along the inclined plane

`F_x = F_g sin\theta`

here we have

`F_g = 112.1 N`

`\theta = 42 degree`

now we have

`F_x = (112.1 N)sin42`

`F_x = 75 N`

so here we require 75 N force along the incline to move the box upwards
