Question 1

Calculate the magnitude of the friction force on a 15 N object that remains at rest on a plane inclined at 45° to the horizontal, when a 2.4 N force parallel to the plane that tends to push it down the plane acts on it.

Accepted Answer

13 N

Question 2

A 24.0 N object remains at rest on a plane inclined at 30.0° to the horizontal under the action of a 3.2 N force that tends to push the object up the plane. Find the magnitude of the friction force on the object.

Accepted Answer

8.8 N

Question 3

Find the magnitude of a force tending to push a stationary 36 N object up a plane inclined at 30.0° to the horizontal, if the static friction force on the object is 8 N.

Accepted Answer

10 N
