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?
A pretty box from taylor swift batumbakal with a mass of 20.0 Kg is moving at a speed of u = 8 m/s. The smooth platform on the top has h = 50 cm from the ground. On the other hand, the rough platform at the bottom and the box has a coefficient of kinetic friction = 0.325. Also, in the bottom platform, the pretty box was able to move by R = 11.0 m before the spring, whose a spring constant k = 390 N/m, is compressed and the box stopping. What must be the initial speed of the box for it to stop just as it touches the spring?
A spring-loaded toy gun is used to launch a 10 g plastic ball. The spring, which has a spring constant of 10N/m is compressed by 10 cm as the ball is pushed into the barrel. When the trigger is pulled, the spring is released and shoots the ball back out horizontally. a) What is the ball's speed as it leaves the barrel? Assume the friction is negligible. b) If the toy gun was shot vertically upward, how high would the ball go? Use energy concepts.

A block of mass 2.9 kg is sitting on a frictionless ramp with a spring at the bottom that has a spring constant of 470 N/m (refer to the figure). The angle of the ramp with respect to the horizontal is 13°. a) The block, starting from rest, slides down the ramp a distance 54 cm before hitting the spring. How far, in centimeters, is the spring compressed as the block comes to momentary rest? b) After the block comes to rest, the spring pushes the block back up the ramp. How fast, in meters per second, is the block moving right after it comes off the spring? c) What is the change of the gravitational potential energy, in joules, between the original position of the block at the top of the ramp and the position of the block when the spring is fully compressed?

A small cart of mass 9 kg slides down from the top of a curved track of unknown length. It first passes a small patch of rough surface, and then it hits a spring of rest length 1.61 m and stops. The spring is also located on a second patch of rough surface. if the spring constant of the spring was 18 N/m, it was compressed from 1.61 m to 0.79 m after the cart had finally stopped, and the velocity of the cart when it first entered the second rough patch was 9 m/s, what was the magnitude of negative work done by friction force from the second rough patch in joules? Use g = 9.8 m/s² in your calculations and retain your answer to two decimal places. m h k www d

A 2-kg block is attached to a spring (k = 600 N/m), where it bounces back and forth without friction. When the spring is compressed 0.1 m from equilibrium, the block has a speed of 2 m/s. What is the fastest speed the block achieves during the bouncing? Answer in m/s. [Hint: If the block only has PE and KE, how much PE will it have when it is going as fast as possible?]
