Solve the all parts of given problemproblem to pull a crate, Ask an Expert

Academics

Solve the all parts of given problem:

Problem: To pull a crate of mass m across a horizontal frictionless floor, a worker applies a force F, directed at an angle theta above the horizontal. As the crate moves forward a distance d,

Part A: What work is done on the crate by the worker's force?

Part B: What work is done by the gravitational force on the crate?

Part C: What work is done by the normal force on the crate from the floor?

Part D: What is the total work done on the crate?

I want help to find what work is done by the gravitational force on the crate.
