You pull a simple pendulum 0.240 m long to the side through an angle of 3.50o and release it. (a) How much time does it take the pendulum bob to reach its highest speed? (b) How much time does it take if the pendulum is released at an angle of 1.75o instead of 3.50o?

Solution 45E The time period of a simple pendulum is given by = 2 g …..(1) Given, L = 0.240 m We know, g = 9.8 m/s 2 Substituting these values in equation (1), we get T = 2 09.80s T = 0.98 s (a) Now, the pendulum will have the highest speed when it is passing the equilibrium position. When the period is T. the pendulum will pass through the equilibrium at time T/4. Therefore,...
