10. A 37.0-kg child swings in a swing supported by two ropes, each 3.10 m long. Find the tension in each rope if the speed of the child at the lowest point of the swing is 5.80 m/s. (ignore the mass of the seat.)

2. A helicopter drops a cable which is attached to a load. The cable is partially reeled in, and the helicopter flies east. Air resistance causes the load to swing backwards such that it makes an angle of 20.0° with the vertical. Draw a FBD of the situation.

A simple pendulum, consisting of a mass of 8.691 kg, is attached to the end of a 3.23 m length of string. If the mass is held out horizontally, and then released from rest, the speed of the mass (in m/s) at the bottom of the swing is:

A child of mass 25.0 kg tries to cross a river by swinging from a vine. The vine is 10.0 m long, and his speed at the bottom of the swing is 7.00 m/s. What is the tension in the vine at the lowest point? Your Answer: Answer Question 14 (3 points) units (Continue the above problem) What is the speed of the child at a point 1.00 meters above the bottom of the swing after passing it? ignore air resistance.
