Problem 3: A thin cylindrical ring starts from rest at a height h, = 82 m. The ring has a radius R = 18 cm and a mass M = 5 kg. R 2 h, h, Part (a) Write an expression for the ring's initial energy at point 1, assuming that the gravitational potential energy at point 3 is zero. Expression: E1 = igh, Select from the variables below to write your expression. Note that all variables may not be required. a, B, 0, a, d, g, h1, h2, j, k, M, P, t, v1, v2 Part (b) If the ring rolls (without slipping) all the way to point 2, what is the ring's energy at point 2 in terms of h2 and v2? Expression : E2 = Select from the variables below to write your expression. Note that all variables may not be required. a, ß, 0, a, d, g, h1, h2, j, k, M, P, t, v1, V2 Part (c) Given h2 = 41 m, what is the velocity of the ring at point 2 in m/s? Numeric A numeric value is expected and not an expression. V2 = 20.05 Part (d) What is the ring's rotational velocity in rad/s at point 2? Numeric : A numeric value is expected and not an expression. 0 = 11.3 Part (e) After passing point 2 the hill becomes frictionless and the ring's rotational velocity remains constant. What is the linear velocity of the ring at point 3 in m/s? Numeric Anumeric value is expected and not an expression. V3 =
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
