A box of mass m is pressed against (but is not attached to) an ideal spring of force constant k and negligible mass, compressing the spring a distance x. After it is released, the box slides up a frictionless incline as shown in the figure and eventually stops at high H. 0000000 Smooth Smooth a. Clearly explain what would change (if anything) if we repeat this experiment with a box of mass 2m b. Clearly explain what would change (if anything) if we repeat this experiment but instead compress the spring a distance of 2x c. Clearly explain what would change (if anything) if we repeat this experiment but instead use a spring having force constant 2k d. What are the energy transformations taking place in this experiment?

A 2.5-kg block is held at rest against a spring (? = 1200 N/m), compressing it ? = 5.0 cm from its equilibrium position, then released. There is no friction except where indicated otherwise. A. Just to the right of point ?, the block traverses a rough section, (represented by the thick line between ? and ?), losing half of its kinetic energy to friction. What is the block’s speed at point ?? B. The rough section described in part (c) is 20 cm long. What isthe coefficient of kinetic friction?
A crate of mass m1 slides down a well-lubricated hill of height h, with negligible friction. At the bottom, where it is moving horizontally, it collides with another crate, of mass m2, that initially was sitting at rest and that is attached to a wall by a spring of spring constant k that initially is at its equilibrium length. Assume that the spring itself has negligible mass. a)Given that the distance d that the crates compress the spring is d=0.35 m, calculate the speed v2 of the crates immediately after the collision, in units of meters per second.

.. .A frictionless spring with a 5-kg mass can be held stretched 1.2 meters beyond its natural length by a force of 90 newtons. If the mass begins at its equilibrium position, but an upward push gives it ar initial velocity of 2.5 m/sec, find the position of the mass after t seconds (where the upward direction is presumed to be positive). Express your solution as a real-valued function. Use g 9.8-m, as needed. sec meters

A 10.0 g bullet is fired into and embeds itself in a 1.80 kg block attached to a spring with a spring constant of 21.5 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block, and the block slides on a frictionless surface? (Note: You must use conservation of momentum in this problem.) m

An inclined plane of angle θhas a spring of force constant k fastened securely at the bottom so that the spring is parallel to the surface as shown. A block of mass m is placed on the plane at a distance d from the spring. From this position, the block is projected downward toward the spring with speed v. Calculate By what distance is the spring compressed when the block momentarily comes to rest? develop an equation for x. x when θ=30.0° , k = 1 kN/m, m = 5 kg, d = 0.5 m, and v =1 m/s. If we add another spring in series, by what distance is the spring compressed when the block momentarily comes to rest? If we add another spring in parallel, by what distance is the spring compressed when the block momentarily comes to rest? Part 3 & 4 are where I am struggling
