Q1. A trapeze artist swings in simple harmonic motion with a period of 7.0 s. The acceleration of gravity is 9.81 m/s^2. Compute the length of the cables supporting the trapeze.
Q2. A man pushes a lawnmower for 13.1 m along a handle that makes a 28.2° angle with the ground. He pushes with a force of 42.8 N even as the force of friction between the lawnmower and the ground is 13.7 N.
