100%

Determine:

a) magnitude of final velocity u2 of m2 after collision

b) direction of motion B (beta) of m2 after collision

c) total kinetic energy of this system before collision

d) was this collision between these two masses elastic or inelastic? pls explain why.. for me to understand well.

 

*pls answer with complete solution

*THREE decimal places all final answers

*provide a diagram (if applicable)

* enclose all final answers with a

box.

 

**pls help me solve this as for my preparation/review on upcoming test.

 

thank you so much

A mass m1 = 6.40 kg is moving toward the left with a velocity of v1 = 11.2 m/s
when it collides with a second mass m2 = 4.60 kg which is initially at rest. After
the collision the first mass bounces off to the right of the initial path of motion
with a velocity of ut 9.50 m/sec at an angle a = 20.4o while the second mass
m2 bounces off to the left of the original path of motion with a velocity u2 at an
angle B as shown in the figure.
