A block of mass m1 = 1.0 kg slides along a frictionless table with a velocity of +10 m/s. Directly in front of it, and moving with a velocity of +3.0 m/s, is a block of mass m2 = 9.0 kg. A massless spring with spring constant k = 1120 N/m is attached to the second block as in the figure below. (b) After the collision, the spring is compressed by a maximum amount Δx. What is the value of Δx? cm (c) The blocks will eventually separate again. What is the final velocity of each block measured in the reference frame of the table? m/s (for m1) m/s (for m2) I am having distinguishing the type of collision. Is this inelastic since the first block will "stick" compressing the spring? but it will soon separate so Im not sure if this is inelastic or elastic collsion. Momentum for M1 = m1 * v1 = 1kg * 10m/s Momentum for M2 = m2 * v2 = 3kg * 9m/s Can someone clarify if this is elastic or inelastic? and how would I approach this problem Thanks.
