A mass m = 2.5 kg is sliding along a frictionless table with initial speed v as shown in the figure. It strikes a coiled spring that has a force constant k = 500 N/m and compresses it a distance x2 – x1 = –5.0 cm. The initial speed v of the block was

A 5.0-kg ball and a 10.0-kg ball approach each other with equal speeds of 20 m/s. If they collide perfectly inelastically, the speed of the balls just after the collision is approximately
