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: B 139

Answer 1

Answer:

$T=98 N + m*9.8\frac{m}{s^2}*cos(22)$

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°).

$T=98 N + m*9.8\frac{m}{s^2}*cos(22)$
