Calculate the speed I of the block of mass M = 27 kg after the collision? The block of mass m = 3.6 kg, moving on a frictionless surface with an initial speed Vi = 8.3 m/s makes a sudden perfectly elastic collision with a stationary block of mass M = 27 kg, as shown in the figure. Just after the collision, the 3.6 kg block recoils with a speed of v f = 2.9 m/s. E M M before after
