    A 1500-kg air conditioning unit is being lifted by a crane onto the roof of a building. The unit starts on the ground and is raised straight up to a height of 12.0 m by a cable attached to the crane. The tension in the cable during the lift is 1.54 × 104 N. (Reminders: a free body diagram will probably be helpful, and work can be positive or negative.) (a) How much work is done on the air conditioning...

    The crane shown in the figure is lifting a 463-kg crate upward with an acceleration of 2.60 m/s2. The cable from the crate passes over a solid cylindrical pulley at the top of the boom. The pulley has a mass of 111 kg. The cable is then wound onto a hollow cylindrical drum that is mounted on the deck of the crane. The mass of the drum is 124 kg, and its radius (the same as that of the pulley)...

    A statue with a mass of 103.1 kg is being lifted by a crane attached to a building. At one point in the lift, the statue is moving upwards with a speed of 5.1 m/s and slowing down (the speed is getting smaller). The magnitude of the acceleration is 1.82 m/s^2. What is the tension in the cable lifting the statue? Give your answer in N to three significant figures. Assume the rope is ideal.

    A crane is being used to lift a container onto a cargo ship. The crane initially lifts the container up with a constant positive (upwards is positive) acceleration, a l i f t . The crane then reduces the tension in the cable so that the container slows to a stop with a constant negative (downward) acceleration, a s t o p = - 3 a l i f t . Assume the acceleration goes directly from upwards to downwards...
