Listen A block moving with speed v1 = 18 m/s and mass m1= 5 kg collides with a block of mass m2 = 8 kg initially at rest. (Both slide on a frictionless surface at all times.) If the first block bounces backwards at a speed of 7.5 m/s, what is the final velocity of the second block? OA) 15.9 m/s B) 19.9 m/s OC) 23.9 m/s OD) 27.9 m/s OE) 31.9 m/s
