Question

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 with no time between the two. The container has a mass of 553.3 kg, the total distance the container is lifted is 9.9 m, and the tension in the cable lifting the container is 6037 N while the container is accelerating upwards. What is the largest velocity of the container during the entire lift?

Answer 1
