Transcribed Image Text:As shown in the figure below, cars #1 and #2 are sliding across a horizontal frictionless surface.
The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together.
You know the mass of each car; m, = 15.5 kg and m, = 47.0 kg. In addition, you are provided with the following graph, which shows the momentum of car #1 before, during and after
the collision.
p (kg · m/s)

t (s)
Determine the velocity (in m/s) of car #2 before the collision.

In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.arrow_forward
