Two objects with masses 5.60 kg and 1.40 kg hang 0.500 m, Ask an Expert

Academics

Q. Two objects with masses 5.60kg and 1.40kg hang 0.500m above the floor from the ends of a cord 6.80m long passing over a frictionless pulley. Both objects start from rest. Find the maximum height reached by the 1.40kg object.

Q. A gymnast of mass 64.0 {rm kg} hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 {rm m/s^2} for the acceleration of gravity.

Calculate the tension T in the rope if the gymnast slides down the rope with a downward acceleration of magnitude 1.50 {rm m/s^2}.
