Question

Two blocks of masses m1 = 1.95 kg and m2 = 3.90 kg are each released from rest at a height of h = 6.00 m on a frictionless track, as shown in the figure below, and undergo an elastic head-on collision. (Let the positive direction point to the right. Indicate the direction with the sign of your answer.) Two blocks are on a curved ramp similar in shape to a half-pipe. There is a flat horizontal surface with opposite ends curving upwards. A block of mass m1 is on the left curved end at a height h above the lowest point of the track. A block of mass m2 is on the right curved end also at a height h above the lowest point of the track.

Two blocks are on a curved ramp similar in shape to a half-pipe. There is a flat horizontal surface with opposite ends curving upwards.

• A block of mass m₁ is on the left curved end at a height h above the lowest point of the track.
• A block of mass m₂ is on the right curved end also at a height h above the lowest point of the track.

(a) Determine the velocity of each block just before the collision.

v1i = 10.85 Correct: Your answer is correct. m/s

v2i = -10.85 Correct: Your answer is correct. m/s

b) Determine the velocity of each block immediately after the collision.

v1f =

v2f =

(c) Determine the maximum heights to which m1 and m2 rise after the collision.

y1f = ____m

y2f = _____m
