I need help with this problem (including all work please).
A wooden pallet with bags of cement is sitting on the wooden floor of a warehouse. The
total mass of the pallet and cement bags is 250.0 kg. A worker needs to pull the pallet
across the floor. She attaches a rope to the pallet and it makes a 30.0° angle with the
horizontal. She exerts a force of 1,200 Newtons on the rope to do this. The coefficient of
friction between the pallet and the floor is 0.25.
a. What are the components of the worker's applied force on the rope?
b. What is the amount of the normal force exerted by the floor on the pallet? .
c. What is the amount of friction that the pallet is experiencing?
d. Does the pallet start moving? i. If Yes: what is its acceleration? ii. If No: how much
more force must the worker exert on the rope to start it moving?
