A 106 kg chesterfield is pushed up a frictionless ramp at a constant speed by a delivery person.
If the ramp is inclined at 28.9° to the horizontal, what horizontal force must the delivery person apply to the chesterfield?
Correct, computer gets: 5.74e+02 N
# 20. [1 point, 10 tries]
What is the magnitude of the normal force that is exerted on the chesterfield by the ramp?
I only get two more tries
