5) A spring with a spring constant of k = 50 N/m has a natural length of 0.45m. It is attached to the top of an incline that makes a 30 degree angle with the horizontal. The incline is 2.4 m long. A mass of 2 kg is attached to the spring, causing it to be stretched down the incline. Har far down the incline does the end of the spring rest? a) 0.2 m b) 0.45 m c) 0.65 m d) 0.835 m e) 1.2 m all along a frictionless floor

3) A linear spring having spring constant K is positioned horizontally along a friction-less horizontal surface One end of the spring is attached to a vertical wall and the other end is attached to a block having mass M. A horizontal x-axis is defined for the position of the block, such that the block is at the origin when the spring is at its “natural" length, ie. not stretched or compressed. Furthermore, stretching the spring results in the block having a positive value of x. a) During a 1s* process, an external agent grasps the block and slowly stretches the spring so that the block comes to rest at x = Xa. Determine an expression {K, M, XA} for the work done by the agent onto the block system during this 1* process. b) During a 2nd process, the agent continues to slowly stretch the spring so that block comes to rest at x = XB Determine an expression {K, M, XA, XB} for the work done by the agent onto the block system during this 2nd process. c) During a 3rd process, the agent…

A bungee jumper falls for 1.3 s before the bungee cord begins to stretch. Until the jumper has bounced back up to this height , the elastic cord causes the jumper to have an average acceleration upward of 4 m/ c) How long after the bungee cord begins to stretch does the jumper reach the low point of the drop?
What happens when the stretching force on an elastic material is no longer applied? Assume the force has not exceeded the elastic limit for the material The material breaks. Nothing happens. The material becomes permanently distorted. The material snaps back to its original shape.
