- A pendulum is undergoing simple harmonic motion. At a particular instant, you measure its speed to be v0,and you notice that exactly half of its energy is potential, and the other half is kinetic. It is a simple pendulum oflength l, with all of its mass (m) concentrated in a point at the end. a) In terms of v0, what is the highest speed the pendulum will reach? b)What is the largest angle that the pendulum will reach?A mass of 1kg is attached to a spring with a spring constant of k=10 N/m. you stretch the spring to distance A from equilibrium and let go. The mass oscillates with a certain period, frequency, and total energy. Now stretch the spring to a distance of 3A. compared to the original total energy E, what is the new total energy of the system now?I'm doing calc1 by myself right now and not sure where to start with this problem: Here are the questions: An object attached to a spring swings vertically around its equilibrium position. The height of the object relative to its position of equilibrium is given by the following function: h(t)=(e^-(x/10)*100sin(x)-10cos(x))/101 *(See photo i have provided)* a) Give the object movement for the first 10 seconds. I know i can find the speed of an object if i have it's acceleration. But how do i find it's movement fom it's height? I have done the integral of the height's equation and it's -(100e^-(x/10)(20sin(x)+99cos(x))/10201+Constant b) Give the total distance traveled by the object during the first 10 seconds I would assume this is something along the lines of finding the final positition of the object and the initial position and substracting them? c) Give the total distance that will be traveled by the object from time t = 0. at this point i am clueless to what i should find I…
- A pendulum of mass 90 gm and length 60 cm is left to swing from an initial angle of 40 degrees, and seen to raise up to an angle of 38 degrees when it reaches the other side. How much energy did the pendulum lose? Why is there a loss of energy?A light elastic string, of natural length 0.8 m and modulus of elasticity 35-4 N, has one end A attached to a fixed point and the other end B attached to a particle P of mass 3 kg. Initially P is held at rest at A. It is then released and allowed to fall. Calculate the speed of P when the length of the string is 1-2 m.A simple pendulum with a bob with a mass of m and a string with a length of L oscillates with a large amplitude in a vertical plane. The maximum speed it attains during an oscillation is v,. The string makes an angle 0, with the vertical at some instant during the course of motion. Use the principle of conservation of energy to find an expression for the magnitude of the tension force on the bob in terms of known quantities and constant.
- The length of a simple pendulum is 0.85 m and the mass of the particle (the “bob”) at the end of the cable is 0.32 kg. The pendulum is pulled away from its equilibrium position by an angle of 7.5° and released from rest. Assume that friction can be neglected and that the resulting oscillatory motion is simple harmonic motion. Using the position of the bob at its lowest point as the reference level, determine the total mechanical energy of the pendulum as it swings back and forth.A harmonic oscillator has angular frequency w and amplitude A. Assume that the elastic potential energy of the oscillator is zero at x = 0. At an instant when the displacement is equal to A/5, what fraction of the total energy of the oscillator is kinetic? Give the final answer to 2 decimal places.
