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.
