Physics 1 Reinforcement Question ______________________________________________________________________________________ ______________________________________________________________________________________ Chapter 8 1/2 ASD2007/08 Reinforcement Questions Chapter 8: Oscillations Question 1: (to get yourself familiar with the equations) Question i to iv refer to a particle, with mass m , attached to a spring, with spring constant k , and moving in simple harmonic motion with amplitude A meters, period T seconds. Its velocity at position x meters from the equilibrium position is v ms -1 . i. When x = 0.3m, magnitude of acceleration is 1.2ms -2 . Given that A = 0.5m, find the period T and velocity v when x = 0.3m. ii. When x = 0.12m, magnitude of acceleration is 0.48ms -2 . Given that A = 0.4m, find the period T and its maximum speed. iii. Given that it makes 20 complete swings in one minute and its maximum magnitude of acceleration is 2ms -2 , find T and A . iv. Given that . 0 25 2 2 = + x dt x d find T . If x = 4m when t = 0 and x = 3 when t = π / 10 s, find A . Question 2:
