Question

A box is pulled up a rough ramp that makes an angle of 22 degrees with the horizontal surface. The surface of the ramp is the x-plane. What is the magnitude of the force of tension if the net force in the x direction of 98 N?

A.)57 N

B.)139 N 1

C.)78 N

D.)183 N

Answer 2

`T=98 N + m*9.8(m)/(s^2)*cos(22)`

Step-by-step explanation:

The balance of forces in the x-plane:

`T-P=98 N`

Where T is the force of tension and P is the wieght force

The weight in an inclined plane:

`P=m*g*cos(a)`

Where m is the mass of the box, g is the gravity force and a is the angle ( in this case 22°).

`T=98 N + m*9.8(m)/(s^2)*cos(22)`
