A toy car of mass 1kg is pushed up against a spring with a spring constant of 500N/m, compressing the spring 0.05m. The spring is released, causing the car to slide across a frictionless track. After a certain distance of track, the car slides up a frictionless ramp of 10 degrees before coming to a stop. a) What is the speed fo the car after it leaves the spring but before it starts up the ramp. (Answer: 1.12m/s) b) What...
A m= 2.00 kg block is pushed against a spring with negligible mass and force constant k= 300. N/m, compressing it d= 0.250 m. When the block is released, it moves along a frictionless, horizontal surface and then up an incline with slope 37.0° and a coefficient of kinetic friction of 0.320. A)What is the speed of the block as it slides along the horizontal surface after having left the spring?B) How far does the object travel up the incline before...
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 block of mass 3.40 kg is placed against a horizontal spring of constant k = 865 N/m and pushed so the spring compresses by 0.0600 m.

A 2-kg block is pushed against a spring with spring-constant k 512 N/m, compressing it 0.25 m. When the block is released, it moves along a frictionless, horizontal surface and then up a frictionless incline with slope 53.1° (a) What is the speed of the block as it slides along the horizontal surface after having left the spring? (b) How far does the block travel up the incline before starting to slide back down?
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...
SPRING PE PRACTICE • A person uses a 10 kg block to compress a spring (with spring constant 8000 N/m) by 0.1 meters. The block is then released and slides along a frictional ramp (lk = 0.2). How far along the ramp does the block slide before coming to a stop? Ax = ? Hy = 0.2 < 0.2 10 kg ww10t04 370
