In this video we will cover:-
1.Does this function represent (a) simple harmonic,(b) periodic but not simple harmonic,or(c) no-periodic motion? Calculate the period (ω is any positive constant]:sin ωt + cos ωt
2..A body oscillates with SHM according to the equation (in SI units), x = 5 cos [2π t + π/4].
At t = 1.5 s, calculate the (a) displacement, (b) speed and (c) acceleration of the body
3.A spring balance has a scale that reads from 0 to 50 kg. The length of the scale is 20 cm. A body suspended from this balance, when displaced and released, oscillates with a period of 0.6 s. What is the weight of the body ?
4.A simple pendulum of length l and having a bob of mass M is suspended in a car. The car is moving on a circular track of radius R with a uniform speed v.If the pendulum makes small oscillations in a radial direction about its equilibrium position, what will be its time period ?
5.A 5 kg collar is attached to a spring of spring constant 500 N m–1. It slides without friction over a horizontal rod. The collar is displaced from its equilibrium position by 10.0 cm and released. Calculate (a) the period of oscillation,(b) the maximum speed and (c) maximum acceleration of the collar.
