Click For Summary
The discussion centers on a physics problem involving a glancing collision between two equal mass objects, each with specified initial velocities. Participants emphasize the need to apply conservation of momentum and kinetic energy principles to solve for the post-collision speeds and determine the nature of the collision. The original poster seeks guidance on calculating the speeds of both objects after the collision and the change in kinetic energy. There is a suggestion to post the question in a dedicated homework subforum for more targeted assistance. The conversation highlights the importance of proper categorization for effective help in academic inquiries.

Hey, I'm stuck on this problem. If someone could point me in the right direction, it'd be greatly appreciated.

: Two objects of the same mass, m = 1.00 kg, are projected towards each other. The first object initially has velocity (20.0m/s)i^. The second object has initial velocity (-10.0m/s)i^ .After the glancing collision, the first object goes off with angle 2.00˚ above the positive x-direction and the second object goes off with angle 5.00˚ below the negative x-direction.

a. What is the speed of object 1 after the collision?
b. What is the speed of object 2 after the collision?
c. What is the change in kinetic energy in the collision?
d. Is this collision elastic or inelastic? Explain.

Welcome to PF!

This appears to be a homework or homework-type question and should be posted in the homework subforum. Doing so will ensure you get the appropriate help from our outstanding staff of homework helpers. (instead of wikipedia surfing armchair scientists like myself)

Thanks!
