Question

A 70.0 kg box is pulled by a 300. N force at an angle of 30.0 to the horizontal. The static and kinetic coefficient of the friction between the box and the floor is s = 0.45 and k = 0.35. (A) Draw FBD of the box. (B) What is the normal force the floor applied to the box? (C) Is the box in motion or at rest? (D) if the box is at rest, how big is the friction force? If the box is in motion, what is the acceleration of the box?

10. (16 pt) A 70.0 kg box is pulled by a 300. N force at an angle of 30.0° to the horizontal.
The static and kinetic coefficient of the friction between the box and the floor is us = 0.45
0.35. (A) Draw FBD of the box. (B) What is the normal force the floor applied
to the box? (C) Is the box in motion or at rest? (D) if the box is at rest, how big is the
friction force? If the box is in motion, what is the acceleration of the box?
