A 30.5 kg mass is hung on a spring (k = 7.32 N/m). The system is displaced 75.0 cm from equilibrium by the mass and then released. What is the total energy of the mass-spring system?

An ideal spring hangs from the ceiling. A 1.25 kg mass is hung from the spring, stretching the spring a distance d = 0.0865 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L = 0.0325 m from the equilibrium position and released. What is the kinetic energy K of the mass at the instant it passes back through the equilibrium position? K = d Equilibrium position wwwwww. www

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?

A 5.1 kg mass sliding on a frictionless surface with speed 6.3 m/s collides with a spring attached to a wall. (a) What is the maximum compression of the spring with a spring constant of 130 N/m from its equilibrium length? (b) The same mass is now sliding on a rough surface such that the kinetic frictional force is 3.4 N. If the speed remains the same as before when it first collides with the spring, what is the maximum compression of the spring from its equilibrium length?

7. A block of mass m slides with constant velocity v down a plane inclined at 0 with the horizontal. During the time interval At, what is the magnitude of the energy dissipated by friction? (a) mgv At tan 0 (b) mgv At sin 0 (c) 1/2 mv3 At (d) The answer cannot be determined without knowing the coefficient of kinetic friction.

A mass of 0.69 kg is is initially traveling at 6.19 m/s across a horizontal, frictionless surface. It then reaches a spring with a fixed end having a spring constant of 334 N/m that is positioned horizontally and initially at equilibrium. The incoming mass will then contact the spring, compressing it as it comes to rest. What is the speed of the mass upon the spring being compressed by 0.173 m from its equilibrium position?

A 0.220-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 5.49 cm from its equilibrium position.   (a) Find the value of F. (Enter the magnitude of the force only.) N(b) What is the total energy stored in the system when the spring is stretched? J(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/s(e) If the surface is not frictionless but the block still reaches the equilibrium position, how would your answer to part (d) change? The block would arrive at a greater speed. The block would arrive at a lower speed.     The block would arrive at the same speed. (f) What other information would you need to know to find the actual answer to part (d) in this case?

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

A block of mass, 1.5 kg is attached and secured to an end of a spring with a spring constant of 10,000 N/cm. The other end of the spring is secured to the wall. The block is pushed against the spring, which compresses the spring to a position of x = -0.04 cm. When uncompressed, the end of the spring that is attached to the block is at a position of x = 0.00 cm. The block/spring system is then released from rest, and the block travels along a rough horizontal track for the length of the spring. At 0.00 cm the surface changes. Can you help me calculate the block's velocity once it leaves the spring? Thank you.

The 10-kg block is released with a speed of 5 m/s when the spring is unstretched. The coefficient of kinetic friction between the block and the inclined surface is 0.2. What is the speed of the block when it has slid 1 m down the surface? k = 200 N/m 5 m/s 30° 4.27 m/s O 3.85 m/s O 5.64 m/s O 3.38 m/s O 7.17 m/s
