Question: A spring with a force constant of 51 N/m is compressed by 1.2 cm in a hockey game machine. The compressed spring is used to accelerate a small metal puck with a mass of 71.2 grams which will then slide up an inclined surface inside the machine. Assume friction is so tiny it may be ignored in this problem. How high in cm above its initial vertical position will the puck rise before stopping (momentarily at least)? Note: Convert units as necessary.

- When a 3 kg mass is hung on a vertical spring, it extends the spring by 2.00 m. What is the spring constant of the spring in N/m? (Assume g = 10m/s2).m A shown in the picture, a 238 g mass slides down a curved incline then collides with a spring. The spring constant of the spring is 106 N/m. Assume that friction is negligble in these problems. (A) If the mass starts from rest at a height of 1.97 cm, what is the final compression of the spring when the mass comes to rest? Assume the spring is initially uncompressed. 2.95 cm (B) If the mass initially compresses the spring 1.14 cm, what is the maximum height the mass rises to on the incline? Assume the mass is released from rest. (C) If the mass is released from rest at a height of 1.97 cm, what is the compression of the spring when the mass has a speed of 45.4 cm/s?Question as an attachment
- k AX A 0.40 kg block is pushed against a spring (k = 7.0 N/m) thereby compressing it by 25.0 cm, as shown in the figure above. After it is released the block travels a total distance of 23.3 cm before coming to rest. What is the coefficient of kinetic friction for the horizontal surface?3You give a crate of mass m = 1.00 kg an initial speed of vi = 4.00 m/s up an incline of θ = 17°. The crate then slides along the incline, reaches a spring of spring constant k = 92 N/m , and compresses the spring by Δs = 15.0 cm before stopping. a) what is the distance d, in meters, along the incline that the crate slides, assuming there is no friction? b)What distance ds, in meters, along the incline had the crate moved when it just touched the spring? c)If there were friction between the crate and incline, what coefficient of kinetic friction would stop the crate after it travels ds (just before it compresses the spring)?
- An object of mass 0.5 kg is propelled up an incline of angle 17 degrees by a spring with a constant of 11.4 N/m. The horizontal surface is frictionless. The coefficient of kinetic friction between the block and the incline is 0.12. If the spring is compressed by 0.6 m, how high (h shown on the figure) will the object go? Answer in m with two decimals. k, x IM 1-?You attach a 2.10 kg weight to a horizontal spring that is fixed at one end. You pull the weight until the spring is stretched by 0.300 m and release it from rest. Assume the weight slides on a horizontal surface with negligible friction. The weight reaches a speed of zero again 0.100 s after release (for the first time after release). What is the maximum speed of the weight (in m/s)? 18.85 x Your answer is off by a factor of 2. Note that the given time is the amount of time to make one half of a period, not a full period. m/s Need Help? Read It Submit AnswerTo measure the static friction coefficient between a 4.96-kg block and a vertical wall, the setup shown in the drawing is used. A spring (spring constant = 491 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.0579 m, what is the coefficient of static friction? Number i Units m
