Two blocks, A and B, are initially in contact and at rest. A spring with spring constant k = 450 n/m is attached to a wall on its left end and is in contact with Block A on its right end; the spring is uncompressed. See Picture 1. Block A is moved to the left, compressing the spring by 0.65 m. Block B remains stationary. See Picture 2. Block A is then released and moves towards Block B. The surface below the blocks has a coefficient of kinetic friction of uk = 0.60. The two blocks then collide, stick together, and move to the right as one object. Block A has a mass of mA= 5.0 kg and Block B has a mass of mB = 3.0 kg. a. How much elastic energy is stored in the spring before Block A is released? See Picture 2 for a visual. b. What is the speed of Block A just before it collides with Block B? c. What type of collision occurs between Blocks A and B?
