A construction crew pulls up an 87.5 kg load using a rope thrown over a pulley and pulled by an electric motor. They lift the load 15.5 m and it arrives with a speed of 15.6 m.s having started from rest. Assume that acceleration was not constant. How much work was done by the ...

A sign is supported by a cable and a horizontal beam.The beam has a length 1.4 m and a uniform mass of12 kg.a) If the cable is attached to the beam at a distance of 1.0 m from the hinge, what is the tension in the cable? (b) If the cable breaks, what is the net torque on the ...

A tow truck is pulling a car out of a ditch by means of a steel cable that is 10.2 m long and has a radius of 0.50 cm. When the car just begins to move, the tension in the cable is 870 N. How much has the cable stretched? COnstant for Steel cable Y=2.0e11

Two factors: 1) the weight of the car is now partially down the cable, it adds to tension: mgsinTheta is the component of weight pulling back on the cable. 2) going up you have mass*acceleration. Total tension: ma +mgsinTheta check my thinking, draw a diagram. A section of an ...
