Three objects undergo successive inelastic collisions. Object A, of mass 400 grams travels east at a velocity of 2.30 m/s towards object B of mass 250 grams which is also travelling east but with a velocity of 1.40 m/s. A and B collide and then undergo a second collision with object C, mass 300 grams travelling at velocity u. Calculate what the velocity of object C is, assuming that after the second collision event all objects come together as one with a common velocity of 0.100 m/s westwards. (Note for your answer, velocities east are positive, velocities west are negative.)

Question
Transcribed Image Text:Three objects undergo successive inelastic collisions. Object
A, of mass 400 grams travels east at a velocity of 2.30 m/s
towards object B of mass 250 grams which is also travelling
east but with a velocity of 1.40 m/s. A and B collide and then
undergo a second collision with object C, mass 300 grams
travelling at velocity u. Calculate what the velocity of object C
is, assuming that after the second collision event all objects
come together as one with a common velocity of 0.100 m/s
westwards. (Note for your answer, velocities east are positive,
velocities west are negative.)
Expert Solution
Step 1
Consider a system of the objects A and B, apply conservation of momentum on the system, and solve for the velocity (v1) of the system after the first collision.
