In a laboratory experiment, 1 a block of mass M is placed on a frictionless table at the end of a relaxed spring of spring constant k. 2 The spring is compressed a distance x0 and 3 a small ball of mass m is launched into the block as shown in Figure P11.22. The ball and block stick together and are projected off the table of height h. Find an expression for the horizontal displacement of the ballblock system from the end of the table until it hits the floor in terms of the parameters given. FIGURE P11.22
An inclined plane of angle = 20.0 has a spring of force constant k = 500 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in Figure P6.61. A block of mass m = 2.50 kg is placed on the plane at a distance d = 0.300 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?

You have been asked to design a "ballistic spring system" to measure the speed of bullets. A bullet of mass m is fired into a block of mass M. The block, with the embedded bullet, then slides across a frictionless table and collides with a horizontal spring whose spring constant is k. The opposite end of the spring is anchored to a wall. The spring's maximum compression d is measured.What was the speed of a 2.1 g bullet if the block's mass is 1.5 kg and if the spring, with k = 40 N/m , was compressed by 15 cm ?
A 400 kg trailer with a spring attached to it is travelling at a speed of 20 m/s. The trailer collides with a 200 kg cart going 40 m/s in a head-on collision. If the spring constant is 850 N/m, calculate the maximum compression of the spring.
The massless spring of a spring gun has a force constant k=12N/cm.k=12N/cm.When the gun is aimed vertically, a 15-g projectile is shot to a height of 5.0 m above the end of the expanded spring. (See below.) How much was the spring compressed initially?
A spring clamped to the table shoots Block 1 (110 g, wood) directly into Block 2 (80 g, steel), this perfectlyelastic collision will launch the second block up a ramp. When the spring is compressed 14 cm, the block travels upa ramp that has a height of 86 cm and then compresses another spring (310 N/m) at the top, 5 cm. What then isthe spring constant for the first spring? Assume that all surfaces are frictionless
