1.)(3pts) A 2 kg hammer is set on a roof for which = .22. The roof has a pitch of
40 degrees. Will the hammer stay on the roof or slide off?
2.)(3pts) A 20 kg particle is subject to two forces that produce a resultant
acceleration of a = 2i – 3j m/s2. If one of the forces is F = -2i + 4j N, find the
3.)(4pts) Two blocks with masses m1 = 5kg, and m2 = 8 kg are connected
by a massless rope, and slide on a frictionless surface as in the figure. Find
the acceleration of the system and the tension in the rope.
