A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m.
A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 25° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk=0.18. In the initial position, where the spring is compressed by a distance of d = 0.12 m, the mass is at its lowest...

A wooden block with mass 1.95 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 35.0degree (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 4.00 m up the incline from A, the block is moving up the incline at a speed of 6.15 m/s and is no longer in contact with the spring. The coefficient of kinetic between the...

6. A 5-kg block is pressed against a spring near the bottom of a 30° inclined plane. The spring, (spring constant 450 N/m) is compressed by 0.50 m.When released, the spring projects the block toward the top of the incline. The coefficient of kinetic friction between the block and the inclined plane is 0.3. (a) What is the speed of the block at the instant the block first returns to its equilibrium length? ans [3.9 m/s] (b) Calculate the speed...

An inclined plane of angle θ = 20.0° has a spring of force constant k = 475 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.25 kg is placed on the plane at a distance d = 0.282 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what...

he figure, a spring with spring constant k = 170 N/m s at the top of a frictionless incline of angle θ 36". The lower end of the incline is distance D = 1.0 m from the end of the spring, which is at its relax length. A 2.1 kg canister is pushed against the spring until the spring is compressed 0.24 m and released from rest. (a) What is the speed of the canister at the instant the spring...

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 relaxed spring (k = 120 N/m) is set up on a ramp inclined at θ
=28 degrees. A mass of 0.012 kg is placed on the
spring, compressing it 0.025 m. It is then released.
a) What is the velocity of the mass once it loses
contact with the spring?
b) How far up the ramp will the mass itself travel
after it is released?
