The mass m = 2kg is found at point A compressing a spring of constant k = 100 [N / m] a distance of x = 20cm. Suddenly the mass m is released and goes through a section circular, then along a horizontal plane and finally up another circular section (all without friction) and finally stops at point D. Find: a) The speed of the mass when it passes through point B. b) The maximum height h reached by the mass m after being shot upwards.

A 2.00 kg block is pushed against a spring with negligible mass and force constant k = 400 N/m compressing it 0.220 m.
A 2.00 kg block is pushed against a spring with negligible mass and force constant k = 400 N/m compressing it 0.220 m. When the block is released, it moves along a frictionless, horizontal surface and then up a frictionless incline with slope 37.0 degree. What is the speed of the block as it slides along the horizontal surface after having left the spring? How far does the block travel up the incline before stops and starts to slide back...
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.
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 i is released the box slides up a frictionless incline as shown in the figure and eventually stops. If we repeat this experiment with a box of mass 2m A) the lighter box will go twice as high up the incline as the heavier box. B) both boxes will have the same...

A 12-kg block is pressed against a spring (spring constant 620 N/mN/m ), compressing it some distance. The block is released from rest and slides across a track as shown in (Figure 1). While most of the track is frictionless, there is a 55-cm section of track that has a coefficient of friction with the block of 0.3. A bit further on, the track ascends into a hill that is 40-cm tall. Part A: What is the minimum compression of...

You push a 0.18 kg block at point 1 to point 0, compressing a
spring (k = 240 N/m) a distance of 0.20 m. You release the block,
and it travels along the track, goes around the first loop (rA=
0.42 m) and then the second loop (rB= 0.89 m)

A spring with a spring constant of 718 N/m lies on a horizontal surface and that surface is y = 0 m to calculate the gravitational potential energy. A mass of 3 kg is compressed 0.45 meters into the spring and held still. After the mass is released it slides over a horizontal surface in which a 3.4 meter portion of the surface has friction with a coefficient of kinetic friction of 0.30. After the horizontal surface, it travels up...
