Question 17 (515108) (Elastic Collisions} = (1 points) On a frictionless surface, a block of mass m 2 kg moves at a velocity of v = +6 m/s (towards the right) headed towards another block of m 1 kg moving at a velocity of V2i -3 m/s (towards the left). The first block has an ideal massless spring mounted to its front side and so the collision between the blocks is perfectly elastic. Which set of final velocities is consistent with this collision? Vf = = +3 m/s v2f+1 m/s 1.3% Vif 0.7% Vf 9 m/s v2 = 0 m/s = -9 ; 88.6% V1f 0.7% 0.7% Vf = 0 m/s; v2f vf +3 m/s V2f= = = +9 m/s ; +3 m/s V2f +6 m/s Vf 0 m/s v2 = = Question 18 (601239) (Elastic Collisions} (1 points) A carnival game consists of a two masses on a curved frictionless track, as pictured below. The player pushes the larger object so that it strikes the stationary smaller object which then slides follows the curved track so that it rises vertically to a maximum height, hmaz. The masses are equipped with elastic bumpers so that the impact between them is an elastic collision. If the larger object has a mass, M = 8.93 kg and the smaller object has a mass of m = 0.743 kg, then with what velocity, vo should the player release the larger object so that the smaller object just reaches the target maximum height of hmax 3.0m above the horizontal portion of the track?
