A block with a mass of 2.0kg is held against a spring with a spring constant of 250 N/m. The block compresses the spring 22cm from its equilibrium position. After the block is released, it travels along a surface of 2.0m that has a coefficient of friction of 0.15. It then travels up a frictionless ramp. The ramps angle is 30.0 degrees. How far up the ramp will the block go?

Below is a conservation of energy problem. The solution to this problem is provided. Assess whether the solution provided is correct or incorrect AND EXPLAIN WHY. = 4.6 kg block is at rest against a horizontal spring that is compressed by 0.40 m. The spring has a spring constant of k₁ 2750 N/m. After leaving the spring, it travels up a 28° incline to a height of 2.8 m. At the top of the hill is a second spring with a spring constant of k₂ = 350 N/m. The horizontal portions are frictionless, but the hill has a coefficient of kinetic friction equal to uk = 0.16. The final velocity of the block is 9.78 m/s. How much is the second spring compressed by when the block comes to a stop against it?

A block of mass 15.0 kg slides from rest down a frictionless 40.0° incline and is stopped by a strong spring with k = 2.90 ✕ 104 N/m.The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed?

A block of mass 14.0 kg slides from rest down a frictionless 40.0° incline and is stopped by a strong spring with k = 2.30 ✕ 104 N/m.The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed?

A 3.0 kg block slides with a speed of 2.3 m/s on a frictionless horizontal surface until it encounters a spring. If the block compresses the spring 5.6 cm before coming to rest, what is the force constant of the spring? What initial speed should the block have to compress the spring by 1.4 cm?

A toy gun uses a spring to project a 5.4-g soft rubber sphere horizontally. The spring constant is 8.0 N/m, the barrel of the gun is 17 cm long, and a constant frictional force of 0.034 N exists between barrel and projectile. With what speed does the projectile leave the barrel if the spring was compressed 6.1 cm for this launch? (Assume the projectile is in contact with the barrel for the full 17 cm.)

An m = 12.0kg block is released from rest on a frictionless incline that makes an angle of 0 = 27.0°, as shown in the figure. Below the block is a spring that has a spring constant of 1.55 × 10¹ N/m. The block momentarily stops when it compresses the spring by 5.50 cm. How far I does the block move down the incline from its release point to the stopping point?

The elastic energy stored in your tendons can contribute up to 35% of your energy needs when running. Sports scientists find that (on average) the knee extensor tendons in sprinters stretch 42 mm while those of nonathletes stretch only 35 mm. The spring constant of the tendon is the same for both groups, 33 N/mm. What is the difference in maximum stored energy between the sprinters and the nonathletes? Express your answer to two significant figures and include the appropriate units. ► View Available Hint(s) AU = μA Value N m

A 250 g block on a 30° ramp with μk = 0.17 is pushed against a spring. The constant of the spring is 1400 N/m and the spring is compressed 13.0 cm. After being released, the block will travel 3.4 m up the ramp (that includes the 12 cm) before shooting off the end. How fast will the block be going when it shoots off the edge of the ramp?
