- A student releases the 4kg bob of a 1.92m long pendulum from the position shown. Neglect loss. What is the pendulum's height (h) above its lowest point? unit What is the pendulum's maximum speed during the swing? unit What is the tension in the string at the lowest point? unit C 27°A marble with a mass of 0.085 kg compresses a spring 5.1 cm. If the spring has a constant k = 150 N/m, what will the velocity of the marble be when it's released?I need the answer as soon as possible
- A 0.293-kg block resting on a frictionless, horizontal surface is attached to a spring having force constant 83.8 N/m as in the figure below. A horizontal force F causes the spring to stretch at a distance of 5.02 cm from its equilibrium position. www (a) Find the value of F. (Enter the magnitude of the force only.) (b) What is the total energy stored in the system when the spring is stretched? (c) Find the magnitude of the acceleration of the block immediately after the applied force is removed. m/s2 (d) Find the speed of the block when it first reaches the equilibrium position. m/sA spring is compressed 0.2 m away from its equilibrium point. If you double the distance of compression, how does that impact the restorative spring force? Group of answer choices The spring force is multiplied by 4 The spring force is multiplied by 2 The spring force is multiplied by ½ The spring force is multiplied by ¼Let's see if you can apply what you learned about conservation of energy information about potential energy, kinetic energy, and total energy of the system. In the figure below, a simple pendulum is represented at various positions of its motion. The pendulum has a mass of 0.82 kg and in figure (a) it is moved to a maximum vertical position of 2.1 m. It is released from that position (starts from rest at the top of its motion, highest position) and is allowed to oscillate back and forth. We assume that there is no air resistance or friction in this example, so the pendulum would continue to oscillate forever unless a force was applied to stop it. We also assume that the acceleration due to gravity is 10 m/s2. Fill in the table below for the potential and kinetic energy of the pendulum mass at the various positions of its motion.Start by calculating the potential energy at the highest position using the fact that PE = mgh. At the highest position, the object is released and thus has no…
