Per Bartleby honor code only 3 subparts of a question can be answered per submission. I have submitted 10, 11, 12, and 13 previously. Please answer 14, 15, 16
Draw the FBD and write the equations of motion for the wheelbarrow descending the hill. What is its acceleration? Problem 14 What is the speed at the bottom of the hill? Problem 15 If the collision between the wheelbarrow and the crate has a coefficient of restitution e = 0.6, how fast does the crate move just after impact? Problem 16 If the wheelbarrow were heavier but Jose' can still fully accelerate it, how would this affect its kinetic energy? The friction force from the ground? The post-collision speed of the crate?

Problems 10-16 Information: Jose' pushes a wheelbarrow consisting of a wheel (mass mw 3 kg, radius r= 0.1 m) and a barrow body (mass mg = 30 kg). He accelerates from rest (state 1) to a velocity of 2 m/s (state 2), when he trips and lets the wheelchair roll down the hill (height h = 2 m, 30 deg angle) to the bottom (state 3), where it hits a crate (mass mc = 20 kg) into motion (state 4). The ground has a friction coefficient of 0.5. Between states 1 and 2, when Jose' is balancing the wheelbarrow, all the weight is on the wheel. After that, the support spike drags along the ground, holding half the total weight, while the other half is on the wheel. H. Problem 10 What is conserved from state 1 to state 4? Select all that apply. (a) Energy (b) Mass (c) Momentum (d) Velocity (e) Work Problem 11 How much work did Jose' do to accelerate the wheelbarrow between states 1 and 2? 665 Problem 12 What constant horizontal force did he apply if the distance between the two states is 10 m? 6.6N Problem 13
