Q1. A 53 kg child sits in a swing supported by two chains, each 2.6 m long. If the tension in each chain at the lowest point is 441 N, find the child’s speed at the lowest point. (Neglect the mass of the seat.) Answer in units of m/s.
(part 2 of 2) 10.0 points Find the force of the seat on the child at the lowest point. Answer in units of N
Q2. A 2.04 kg mass attached to a light string rotates on a horizontal, frictionless table. The radius of the circle is 0.863 m, and the string can support a mass of 39.3 kg before breaking. The acceleration of gravity is 9.8 m/s 2 . What maximum speed can the mass have before the string breaks? Answer in units of m/s
