speed of 300.0 m/s is fired into and passes through a 3.00-kg block, as shown in the figure. The block, initially at rest on a frictionless horizontal surface, is connected to a spring with a spring constant of 1000.0 N/m. If the block moves 5.00 cm to the right after impact, Find the speed at which the bullet emerges from the block. a. b. Find the loss of kinetic energy during the collision. www.

A 0.454-kg block is attached to a horizontal spring that is at its equilibrium length, and whose force constant is 23.0 N/m. The block rests on a frictionless surface. A 5.90×10−2-kg wad of putty is thrown horizontally at the block, hitting it with a speed of 8.96 m/s and sticking.How far does the putty-block system compress the spring?

A bullet with a mass m, = 12.7 g is fired into a block of wood at velocity v, 253 m/s. The block is attached to a spring that has a spring constant k of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass mw of the wooden block. mw = kg

A 0.650 kgkg block is attached to a spring with spring constant 14.0 N/mN/m. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 46.0 cm/scm/s. What is the block's speed at the point where x=0.20 A?

A 2.00-kg pendulum ball is attached to a light-uniform cable of length 1.20 m that is hanging from the ceiling at an angle of 50.00 to the vertical. When the pendulum ball is released from the rest position, it swings to the very bottom of the motion where it collides head-on with a 1.40-kg block that is initially at rest on a level surface. lí the pendulum ball recoils at 1.50 m/s, what is the speed of the block after the collision? e = 50° 1.2 m 2.0 kg 1.4 kg a. 5.98 m/s b. 3.88 m/s c. 6.29 m/s d. 4.75 m/s e. 3.03 m/s

Problem 16:   A massless spring (with force constant k = 182 N/m) connects a wall and a block of wood. The system is initially at rest, with the spring unstretched. The block has mass M = 50.1 g and is able to move without friction on a table. A gun is positioned to fire a bullet of mass m = 6.6 g into the block along the spring axis. After the gun is fired, the bullet gets embedded in the block, and the spring is compressed a maximum distance d = 0.97 m.  Part (b)  In meters per second, what is the speed of the bullet v before it enters the block?   Part (c)  What is the frequency f (in Hz) of the resulting periodic motion of the block/bullet and spring system?

A spring with a spring constant 247 N/m is initially compressed by a distance of 0.044 m from its equilibrium position. A mass of 0.059 kg is then held against the compressed spring and released from rest while upon a horizontal, frictionless surface. Assuming that the spring then pushes the mass across the surface, with speed does the mass leave the spring? Assume proper SI Units.
