A block of ice slides 500 m down along a frictionless slope (slopes 20 degrees below horizontal). The slope flattens out at the bottom and there is a very large ideal spring sitting on level ground just beyond the end of the slope.
a.) what is blocks speed at end of slope?
b.) If the block hits the spring and compresses it, what is the maximum compression (i.e change in length) of the spring due to the block hitting it?
