A block of mass m slides with speed along a frictionless, horizontal surface toward an unstretched spring attached to a wall, as shown above. The block compresses the spring a maximum distance Ax. Which of the following values of block mass and initial speed would result in the same maximum compression distance Ax for the spring? (C) Block Mass 2mm Block Mass 2m Block Mass 4m Block Mass Am Initial Speed 11/4 Initial Speed 20 Initial Speed 1/4 Initial Spoed v/2 E 00000000
