A 21.1 g object is attached to a horizontal spring with a spring constant of 23 N/m and released from rest with an amplitude of 12.75 cm. What is the velocity of the object when it is 1/5 of the way to the 12.75 cm position,from the equilibrium position, if the surface is frictionless? The speed is (in MKS units)

A horizontal spring is lying on a frictionless surface. One end of the spring is attaches to a wall while the other end is connected to a movable object. The spring and object are compressed by 0.058 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 11.0 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.031 m relative to its unstrained length?

A 250-g object connected to a light spring with a spring constant of 1.00 N/m sits on a frictionless horizontal table. Suddenly, the object is knocked by a force causing it to move towards right and then vibrate back and forth with an amplitude of 10.0 cm as shown in the drawing. In which positions does the oscillating mass possess maximum kinetic energy? wwwwww ww A 711 ☐ ☐ 1-3T/4 6 t-3T/4 -A 8 Position 2 Position 6. Position 5. 1-7/2 t-T/4 3 X 0 +A Position 3. 1.

A simple pendulum has a period of 2.7 s and an amplitude of 5.0 cm. The mass of the bob is 5 g. Calculate the maximum kinetic energy of the pendulum and give your answer micro Joules (μJ).

A simple pendulum, consisting of a mass of 2.0 kg, is attached to the end of string with unknown length. The mass is held out horizontally, and then released from rest. What must be the length of the string (m) if the speed of the mass at the bottom of the swing is 3.3 m/s?

A pendulum is created with a string of length L, fixed at the top. A ball with mass m is fastened to the bottom. The ball is pulled to the side through an angle theta anrd released. What is the speed of the ball at lowest point? L=1.90 Theta=29.0 Mass=600kg

A 1.1 kg particle is in simple harmonic motion in one dimension and moves according to the equationx = (3.3 m)cos[(π/5 rad/s)t - π/4 rad]with t in seconds. (a) At what positive value of x is the potential energy of the particle equal to half the total energy? (b) How long does the particle take to move to this position x from the equilibrium position? Assume the particle starts out traveling in the +x direction.

A particle undergoes simple harmonic motion with angular velocity of 3.0 rad/s and amplitude of 0.5 m. It starts with maximum forward displacement at time t = 0. Find the velocity at time t = 2.0 s

A 50.0 g mass is attached to a horizontal spring with a spring constant of 15.0 N/m and released from rest with an amplitude of 30.0 cm. What is the velocity of the mass when it is halfway to the equilibrium position if the surface is frictionless?m/s

A 5.80 g toy cow is attached to a spring that has a spring constant of 4.60 N/m. The spring is stretched some unmeasured distance and released so that it begins to oscillate. The total energy of the system is measured as 0.828 J. What will the speed of the mass-spring system be when it is 18.2 cm away from its equilibrium position?
