Use Newton's second law.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)
