A child sitting on a swing is given a horizontal impulse H by a parent. Using the solution to the equation of motion of a pendulum, determine the required magnitude of H if the mass of the child and the seat is 15 kg and the length of the swing is 2m for the following values of peak angle of swing: 5°, 10°, 15°, 20°, 25°, 30°. Take the mass of the child and seat as being concentrated at a point 2 m below the axis of the swing. Neglect the mass of the chain and the effect …
