A block of mass m= 5.9 kg slides from left to right across a frictionless surface with a speed Vi= 8.3 m/s. It collides with a block of mass Mthat is at rest. After the
collision, the 5.9-kg block reverses direction, and its new speed is vf=2.5 m/s. The block of mass M travels to the right at a speed 7 of 3.8 m/s. What is M?
O 7.9 kg
O 23 kg
O 12 kg
O 17 kg
O 9.3 kg
