15 k and u A block of mass m is on a frictional slope with kinetic and static coefficients of friction s= 2"k. The mass of the spring can be ignored. The block is released from a distance of D meters above the spring, and the angle of the slope with respect to the horizontal is theta degrees. What is the maximum compression of the spring?

To measure the spring constant of a certain spring, a student put a mass of 700 g at the bottom of the spring, and the spring stretches by 35.0 cm. What is the spring constant?
#33 The block shown lies on a horizontal frictionless surface, and the spring constant is 62 N/m. Initially, the spring is at its relaxed length and the block is stationary at position x = 0. Then an applied force with a constant magnitude of 4.1 N pulls the block in the positive direction of the a axis, stretching the spring until the block stops. When that stopping point is reached, what is the position of the block in meters? x = 0 Block F = 0 elllllll attached to spring

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. Use the following values:k=950 N/mm1=2.4 kgm2=2.6 kgμ=0.49g=9.8 m/s2 b)What was the speed of the crate of mass m1 just before the collision with the second block, in meters per second? c) What is the height h of the hill, in meters?
In the figure, a 3.8 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is vo = 6.7 m/s, the height difference is h = 1.2 m, and k = 0.554. Find d. μ = 0 Number Units
