You push a 2.5 kg block against a spring, compressing the spring by 35 cm. Then you release the block, and the spring sends it sliding up the inclined plane. The spring constant is. k = 197 N/m and the coefficient of kinetic friction is, mu_k = 0.31, theta = 38 degree. How far along the incline does the block slide from the compressed position when it is released?
A 2-kg block is pushed against a spring with spring-constant k 512 N/m, compressing it 0.25 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?

3. A block of mass m 1.9 kg is held against a spring of spring constant k 410 and compressed 0.75 m. When released, it is pushed along the frictionless surface towards mi rebounds mass m 4.3 kg. The two masses collide and mass towards the spring at a speed of 2.1 m/s, while mass m slides back towards the spring at a sp a. What is the speed of mass mi right before the collision? b. What is...

A spring is used to fire a 100-g block horizontally. The spring has a spring constant of 20 N/m and is initially compressed by 5.0 cm. The block is initially at rest. a) What is the initial elastic potential energy? b) The spring is released. The block leaves the spring when the spring is at its relaxed state. What is the kinetic energy of the block as it leaves the spring? c) After the block leaves the spring, it enter...
A block of mass 1.8 kg is attached to a horizontal spring that has a force constant 900 N/m as shown in the figure below
A block of mass 1.8 kg is attached to a horizontal spring that has a force constant 900 N/m as shown in the figure below. The spring is compressed 2.0 cm and is then released from rest. (a) A constant friction force of 3.4 N retards the block's motion from the moment it is released. How much is the spring compressed when the speed of the block is a maximum. (b) What is the maximum speed?

A block of mass 3 kg is pushed against a spring of spring constant 3000 N/m. Initially, the spring is compressed by a distance of 0.220 m, when the block is released from rest and travels along a horizontal frictionless surface before encountering a frictionless ramp, inclined at an angle of 37° above the horizontal. How far along the ramp does the block travel before momentarily coming to rest?

2. Mass mi 10.0 kg is initially held against the spring of spring constant k 100 N/m. The spring is compressed a distance x 0.45 m. When released, m, is fired towards a block of mass m 4.4 kg initially at rest at the edge of a horizontal, frictionless table of height h- 0.75 m. A ramp is placed at the end of the table. The ramp has a coefficient of kinetic friction μ-0.25 and is a distance d...
