A block of mass m = 4.4 kg, moving on a frictionless surface with a speed v = 9.2 m/s makes a perfectly elastic collision with a second block of mass M, as shown in the figure. The second block is originally at rest. Just after the collision, the 4.4-kg block recoils with a speed of v = 2.5 m/s. What is the mass M of the second block? V M M before after Hint: Elastic collision with the second mass at rest. Define a positive x-direction and be careful with algebraic signs of velocities. Solution takes three or four lines of basic algebra. O 4.4 kg O 2.7 kg O 9.3 kg O 7.7 kg
