In the figure, a block of mass m = 2.9 kg, moving on a frictionless surface with a speed of vi = 4.1 m / s makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 2.9 kg block recoils with a velocity of vf = 0.8 m / s. What is the speed of the block of mass M after the collision? Answers: a) 4.1 m/s b) 4.9 m/s c) 3.7 m/s d) 3.3 m/s e) 4.5 m/s
