7. A block of mass 1.6 kg is attached to a horizontal spring that has a force constant of1000 N/m as shown in Figure a. The spring is compressed 2.0 cm and is then releasedfrom rest as in Figure b.(A) Calculate the speed of the block as it passes through the equilibrium position x 0if the surface is frictionless.(B) Calculate the speed of the block as it passes through the equilibrium position if aconstant friction force of 4.0 N retards its motion from the moment it is released.

A spring is compressed 8.00cm to launch a 35.0g ball horizontally along a frictionless tabletop. The ball rolls off the edge of the table and falls 1.60m to the floor where it hits the floor with a speed of 19.0m/s. What is the spring constant of the spring?. Single line text.
4. A large block with a mass of 8.5 kg slides along a horizontal surface without friction. The block runs into a horizontal spring with a spring constant of 260 N/m and compresses the spring by 50 cm before coming to a stop. How fast is the block moving when it just hit the spring? What is the potential energy of the spring, the kinetic energy of the block, and the total mechanical energy of the system when the block is halfway to its stopping position? That is, find these quantities when the block is at 25 cm and still moving.
4. A 1.00 kg object slides to the right on a surface having a coefficient of kinetic friction 0.250. The m object has a speed of vị 3.00" when it makes contact with a light spring that has a force constant S of 50.0 N/m. The object comes to rest after the spring has been compressed a distance d. The object is then forced toward the left by the spring and continues to move in that direction beyond the spring's unstretched position. Finally, the object comes to rest a distance D to the left of the unstretched spring. a) Find the distance of compression d b) Find the speed v at the unstretched position when the object is moving to the left c) Find the distance D where the object comes to rest. k a m b ,= 0 www. v = 0 e +D→
A spring with spring constant k = 190 N/m is suspended vertically with its upper end fixed to the ceiling and its lower end at position y = 0. A block of weight 21 N is attached to the lower end, held still for a moment, and then released. If K = the kinetic energy, ΔUg = the change (from the initial value) in the gravitational potential energy, and ΔUe = the change in the elastic potential energy... What are (j)K, (k) ΔUg, and (l) ΔUe when y = –20 cm?
