A block of mass m = 4.4 kg, moving on frictionless surface with a speed vi = 9.2 m/s, makes a sudden 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 V4 = 2.5 m/s. before after (a) What is meant by an elastic collision? There are two conditions. Explain what each of these are. (b) For the first of the two conditions, explain how to apply it to the situation above. Include the numerical values, signs where appropriate. Do not solve for anything. (c) For the second of the two conditions, do the same. Again, do not solve for anything. Note: the equations you set up in (b) and (c) will allow you to solve for M and V but you don't have to solve for eithe
