Amover in a moving truck is suing a rope to pull a 400-pound box up a ramp that has an incline of 25o. what is the force needed to hold the box in a stationary position to prevent the box from sliding down the ramp?

F = -52.8 N

Step-by-step explanation:

Given :

Inclination angle : 25°

Weight, W = 400 lb

The force N will push the box against the ramp.

Therefore, Force F will prevent the box from sliding down the ramp.

F = W sin 25°

  = 400 x (-0.132)

  = -52.8 N ( negative sign shows that the force applied in the opposite direction )

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
