A baby is placed in a swing at the end of a 1.50 meter long lightweight rope. The mass of the swing and the baby is 13.00kg total. The swing is lifted to a height of 0.80 m above the bottom of the swing and released from rest. What is the tension in the rope as it swings through the bottom?

A stuntman whose mass is 70 kg swings from the end of a 4.0-m-long rope along the arc of a vertical circle. Assuming he starts from rest when the rope is horizontal, find the tensions in the rope that are required to make him follow his circular path (a) at the beginning of his motion, (b) at a height of 1.5 m above the bottom of the circular arc, and (c) at the bottom of the arc

A pendulum rod has a length L and has a mass m at the end. The pendulum is released from rest at an angle θ away from straight down. (In this problem you may neglect friction and mass of the pendulum arm.) What will the velocity of the mass be at the bottom? What will the tension in the pendulum arm be as it rotates through the bottom of its swing? A person holds the pendulum in place before it...

An acrobat swings on a 34.0 m long cable initially inclined at an angle of 32.0° with the vertical. (Assume the cable has negligible mass.) a) What is the acrobat's speed (in m/s) at the bottom of the swing if he starts from rest? b) What is the acrobat's speed (in m/s) at the bottom of the swing if instead he pushes off with a speed of 5.60 m/s?
