9. A block with a mass of 1.9 kg is held against a spring constant 249N/m. The block compresses the spring 21 cm from its equilibrium position. After the block is released, it travels along a frictionless surface and then up a frictionless ramp. The ramp's angle of inclination is 28° a. Determine the elastic potential energy stored in the spring before the mass is released. b. Calculate the speed of the block as it travels along the horizontal surface. C. Determine how far along the ramp the block will travel before it stop.

Question 6 When a student stretches a spring, what is the flow of energy? a. Energy goes into the spring and into the student. X b. There is no change in the energy of the spring, only for the student. c. There is no change in the energy of the student, but there is a change for the spring. d. Envery leaves the spring and goes to the student. e. Energy goes into the spring from the student.

A 500-g block is released from rest and slides down a frictionless track that begins 2.28 m above the horizontal, as shown in the figure below. At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with a spring constant of 34.5 N/m. Find the maximum distance the spring is compressed. m 500 g h

A block of mass m=1.2 kg is attached to a horizontal spring of force constant k=75 N/m. The block is pushed, and spring is compressed, to the position 10.0 cm to the left of the equilibrium position; then, block is released. A. Neglect friction. Find the speed of the block as it passes through the equilibrium position. B. If the friction is significant and µ = 0.22, what is the speed of the block as it passes through the equilibrium position? Please show the detailed solution, Thank you
