) A family sets up an inclined plane to slide a 350 kg piano onto the back of a truck. The back of the truck is 81 cm above the ground, and the inclined plane is 3.0 m long. An average force of magnitude 1.5 x 103 N is needed to slide the piano up the ramp. a) Determine the work done by the family in loading the piano. b) Calculate the efficiency of the inclined plane used to load the piano B) Procopio is disgusted with his computer and decided to give it a whack. If his hand is in contact with the computer for 100.0 milliseconds
This is energy efficiency and the impulse momentum theorem. Can someone please show me how to compute this? With explanation and illustration/diagram please? Thank you.
