Question

1. A broken clothes drier with a mass of 128 kg is hurled from a cliff 12.6 m high with an initial velocity of 14.5 m/s, directed at an angle of 39.8 above the horizontal. How much work is done on the drier by its own weight during its fall from the cliff to the ground? 2. A 2.62 kg particle moving along the x - axis experiences the force shown, where Fmax=7.40 N, Fmin= - 7.40 N, d1=1.18 m, d2=2.36 m, d3=3.54 m, and d4=4.72 m. At x=0.00 m the particle's velocity is 3.44 m/s. a) What is its velocity at x=2.36 m? b) What is its velocity at x=4.72 m?
