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.

Answer #1

Two blocks of masses m1 = 2.00 kg and m2 =
4.00 kg are released from rest at a height of h = 5.00 m on a
frictionless track as shown to the right. When they meet on the
level portion of the track, they undergo a head-on, elastic
collision. Determine the maximum heights to which m1 and
m2 rise on the curved portion of the track after the
collision.
h1 = m
h2 = m

Two blocks of masses m1 = 4.64 kg and m2 = 7.01 kg are placed on
a frictionless horizontal surface. A light spring is placed between
the blocks and the blocks are pushed together with the spring
between them and released. m1 kg moves to the right with a speed of
7.4 m/s. Determine the speed of the other mass. (Hint: Momentum is
conserved!)

Two blocks with masses m1 = 1.10 kg and m2 = 3.50 kg are

is frictionless, and calculate the speed of the blocks after they
have moved a distance 68.0 cm.

are the final speeds of (a) m1, (b)
m2, and (c) m3?

Two blocks of mass m1 = 9.20 kg and m2 are connected by a light
