Question

5. [1pt] Consider a perfectly elastic collision between two objects of equal mass. Object 1 is initially moving with a velocity v = 3.07 m/s while object 2 is at rest. What are the final velocities after the collision? Enter the final velocity of object 1 first. Correct, computer gets: 0.002+00 m/s, 3.07e+00 m/s 6. [1pt] If the objects have masses m = 2.37 kg and m2 = 4.94 kg, what are the final velocities of the objects after the collision if it is perfectly elastic? Enter the final velocity of object 1 first. Answer 1 of 2: Submit All Answers Answer 2 of 2: Not yet correct, tries 1/15 7. [1pt] If the objects stick together after the collision (a perfectly inelastic collision), calculate their final velocity. Submit All Answers Answer: Not yet correct, tries 1/15

Answer 1

6 According to data velociday of object L K = 3,07mis initiat Final velocity of object be vt - ? Initial velocity of object 2 y = 0 Final Velocity of object 3 be vote mass of abject I m, 2.37kg Maps af object & m. = 4.94kg We know the centre collinen so vt = cm, - mg) v.
