Assessment Provide a complete solution for each problem. Use illustrations/diagrams to visualize the given problem. 1) A family sets up an inclined plane to side 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. aj Determine the work done by the family in loading the piano. bj Calculate the efficiency of the inclined plane used to load the piano, 21 Procopio is disgusted with his computer and decided to give it a whock, If has hand is in contact with the computer for 100.0 milliseconds with a force of 100.0 N, what Impulse did he impart to the computer 3) You are pushing a 10000.0 g box of dishes across the kitchen floor at a rate of 4.0 m/sec. What is its momentum# 4) Harry is standing on an ice rink when another skater hits him, importing a force of 200.0 N for 0.20 seconds. If he has a mass of 90.0 kg. what is his final speed? 5) Roque is driving a bumper car at EK at 18 m/sec, and he hits another car which is at rest. If he ends up going at 6.0 m/sec, what is the final speed of the other cor, given that both cars have 100.0kg mass, he has 80.0 kg mass, and the other person has a mass of 70.0 kg
