Question

My Notes 5. -/11 points oscolPhysAP2016 7.1.WA.003. In a shipping yard, a crane operator attaches a cable to a 1,060 kg shipping container and then uses the crane to lift the container vertically at a constant velocity for a distance of 40 m. Determine the amount of work done (in J) by each of the following. (a) the tension in the cable (b) the force of gravity

Answer 1

Velocity of constant so net @ Wgranty + Wtandsion force is zero o -mgh t W tension = 0 W tension = 10Go x 9.8 x 40 Wtension = 415.52 I I Wgravity = - migh W geavity = - 4150525
