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...

A crane is being used to lift a container onto a cargo ship. You need to program the crane so that it lifts the container with a constant positive acceleration, a, during the first half of the lift and with a constant negative acceleration of the same magnitude, -a, during the second half of the lift. You want to do this so that the maximum speed of the container during the lift is 8.1 m/s. The containers are initially at...

(a) An elevator of mass m moving upward has two forces acting on it: the upward force of tension in the cable and the downward force due to gravity. When the elevator is accelerating upward, which is greater, T or w? T w Both forces are equal. (b) When the elevator is moving at a constant velocity upward, which is greater, T or w? T w Both forces are equal. (c) When the elevator is moving upward, but the acceleration...
