Two masses m, and m₂ are placed on a horizontal plane without friction. A mass is placed between the two masses. The masses are pushed one against each other such that the spring is compressed by an amount Ax. The two masses are then released and let free to slide on the plane. The first one (m₂) moves to the left with initial velocity voi, climbs up on an incline up to a height of h-5cm with final velocity v₁-8m/s. The second one m₂ moves to the right on the horizontal plane with velocity voz. Knowing that m₂=3m₁ compute: a) The velocity Voz of the second mass after the spring has decompressed (note that the values Of the masses, the spring compression and the spring constant are unknown). uppose now that m₁ = 0.5 Kg, m₂ = 1.5 Kg, Ax = 10 cm. b) Compute the elastic constant k of the spring.
