need help to find the answer and the formula and not the answer from chegg used please A 2.0-kg mass is attached to a vertical spring. The mass is held in place with the spring relaxed, and then released from rest. As the mass falls, it stretches the spring. If the spring has a force constant of 100 N/m, how fast is the mass moving after is has descended 3.0 cm? Ignore air resistance. Type in your numeric answer, and then explain how you determined

Give me right solution according to the question Note: Diagram not given. A 1kg block is placed at an inclined sloped at 10 degrees with the horizontal and is pushed up by a 150N force for 3 seconds from which then the 150N force is then removed. The block will continue sliding upward due to is momentum until it will completely stop. How far has the block traveled? if the coefficient of friction is 0.3 between the block and the inclined plane.

ONLY question 2 b) so what I would like you to do is read the questions and read the feedback and fix my answers thats all here is the question : Here is the feedback : You still did not take into consideration that the combined masses are moving when the spring is compressed. Find speed of combined mass at maximum compression using Momentum equation PTI = PTF and then use Energy Equations to solve for the spring constant. Ek1 + Ek2 = EkT + EE Where EE is the elastic energy stored in the spring. Then use EE = 0.5kx2 to solve for k here is my answer : fix it correctly and give me the final answer :
