Need neat and clean handwritten solution 

pastai 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. 1 (2) 3 4 H What is conserved from state 1 to state 4? Select all that apply. Energy Mass Momentum O Velocity
