Question: part a what is the minimum pushing force required to...

Question details

3. 1760 0 The engine block from Dr. Lee Hans carbage is pushed on the floor as shown. The block weighs 40 lbs and the angle

Part A.: What is the minimum pushing force required to move the block?
(include units with answer)

Hint for Part A: Normal force is not the weight; it also includes component of push force

Part B: The block is moving and is still being pushed with the force found in part A. What is the magnitude of the friction force?
(include units with answer)

Hint for Part B: Moving, so what coefficient of friction do we use?

Part C: The block is moving and is still being pushed with the force found in part A. What is the magnitude of the acceleration of the block?
(include units with answer)

Hint for Part C: What is net force in horizontal direction?
