A block of mass 0.250 kg is placed on top of a light, vertical spring of force constant 5 000 N/m and pushed downward so that the spring is compressed by 0.100 m. After the block is released from rest, it travels upward and then leaves the spring. To what maximum height above the point of release does it rise?
A block A, of mass m = 10 Kg, compresses a spring of constant K = 1000 N / m in a length x = 3 cm. Starting from rest, the block is released, which moves from that moment on a horizontal surface without friction until it collides with another block B of mass m = 40 Kg, which was at rest. (Perfectly inelastic shock) and together they go up the channel (inclined surface) without friction, to later continue along a second horizontal plane without friction, at a height h with respect to the first (see Figure). Determine the energy variation that occurs in the collision .
Bumper car "A' , with mass 54.0 × 104 kg, coasts across a level track at 4.50 m/s when it collides elastically with a spring-loaded bumper car "B" at the end of the track. If the maximum compression of the spring during the collision is 1.80 m , what is spring constant of the spring on bumper car "B"?
A box of mass m = 0.12 kg is set against a spring with a spring constant of k1 = 595 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = 158 N/m. The box is not connected to the first spring and may slide freely. How far, d2 in meters, will the second spring compress when the box runs into it? How fast, v in meters per second, will the box be moving when it strikes the second spring? Now assume that the surface is rough (that is, not frictionless). You perform the experiment and observe that the second spring only compresses a distance d2/2. How much energy, in joules, was lost to friction?
A block of mass m2 = 10.0 kg, at rest on a horizontal surface that has negligible friction, is connected to a spring which is initially not stretched or compressed. The other end of the spring is fixed to a wall, and the spring constant is k = 90 N/m. Another block of mass m1 = 14.0 kg and speed v1 = 3.2 m/s collides with the 10.0 kg block. The blocks stick together, and compress the spring. What is the maximum compression of the spring?
A block having a mass of 1.0 kg is given an initial velocity v= 6 m/s to the right and collides with a spring whose mass is negligible and whose force constant is k =100 N/m . Assuming the surface to be frictionless, e the maximum compression of the spring after the collision m 6 m 5 m None
A spring with a spring constant of 335 N/m is initially compressed by a distance of 0.045 m from its equilibrium position. A mass of 0.045 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.
On a flat, frictionless table, two blocks (B1 of mass 2.00 kg and B2 of mass 3.00 kg) are pressed together against either end of an ideal massless spring. The spring stores 75.0 J of elastic potential energy. The blocks are not attached to the spring. What will the coefficient of restitution be if both blocks are released simultaneously?

A block of mass m and speed v collides with a spring,compressing it a distance ∆x. What is the compression of thespring if the force constant of the spring is increased by a factorof four?
Fleas are agile, wingless insects that feed on the blood of their hosts. Although they are typically 2–3 mm long with a mass of 4.6×10−4 kg , they have an astonishing ability to jump when threatened. Their propulsion, which can briefly produce accelerations more than 100 times that of gravity, comes not from muscles but, in fact, from an elastomeric protein called resilin, which acts as a spring. Given that the typical launch velocity of a flea is about 1 m/s, what total energy must be stored in the resilin just before the flea jumps?
A ball of mass 160 g is dropped from a height 1.5 m and bounces off the floor with a velocity 3.0 m/s [Up]. If the average Force on the ball from the floor is 15 N [up], for how long is the ball in contact with the floor in milliseconds?
