Problem 10.71 A 21 kg box slides 4.0 m down the frictionless ramp shown in the figure(Figure 1), then collides with a spring whose spring constant is 200 N/m Part A What is the maximum compression of the spring? Express your answer to two significant figures and include the appropriate units. HA Asmax = Value Units Submit Request Answer • Part B At what compression of the spring does the box have its maximum speed? Express your answer to two significant figures and include the appropriate units. As = Value Units Submit Request Answer Provide Feedback

I have no idea how to start this problem how do I do it.

Please answer the question correctly

Please the question correctly and clearly please

please can you try again? This answer is wrong. Thank you

You throw a 3.00 N rock vertically into the air from ground level. You observe that when it is 16.0 m above the ground, it is traveling at 24.0 m/s upward. You do not have to show your work

Using the geometrical approach based on areas just described in question 1, you can find the total work done by the approximate force over the displacement between x = 0 and x = x2. What is this approximate work for the case of N = 4?

A 20kg block starts from rest and slides 6m down an incline as shown below. The block then hits a spring that has a force constant of 200 N/m. The angle of the incline is 30° and there is a coefficient of kinetic friction equal to 0.2 between the block and the incline. HK = 0.2 6m K = 200N/m www 300 Answer the following questions on your own paper and staple it to this sheet. 1. What is the speed of the block as it hits the spring? 2. At what distance from the top does the maximum speed occur? 3. What is the maximum speed of the block? 4. What is the total distance that the spring gets compressed? The spring recoils to push the block back up the incline. 5. What will be the speed of the block when it leaves the spring? 6. How far up the incline will the block travel? (above the spring)
