The picture below shows a block of mass 5.22kg held against a spring of spring constant compressed by a distance d = 28.3cm on a frictionless ramp of length . The ramp has an angle of 20°. A distance x = 1.16m separates the ramp from a landing area that is at the same height as the top of the ramp. http://session.masteringphysics.com/problemAsset/1000182266/40/114-24-1.png 1.If the mass leaves the end of the spring at a speed of 4.43 , what is the spring constant of the spring? 2.If the mass reaches the top of the ramp moving at speed 2.81 , what is the length of the ramp? Measure the length of the ramp from the starting point (compressed spring) as shown in the picture. 3. Does the mass successfully jump the gap and land on the other side? I thought I could use W(work) = PEg+KE but that is as far as I got if someone could walk me through this I would greatly appreciate it I have a final next week on this and I want to make sure I'm doing it right.
