Two objects of masses m and 7m are moving toward each other along the x-axis with the same initial speed

v0 = 765 m/s.

The object with mass m is traveling to the left, and the object with mass 7m is traveling to the right. They undergo an elastic glancing collision such that m is moving downward after the collision at a right angle from its initial direction.

(a) Find the final speeds of the two objects.

m= ____

7m= ____ m/s

(b) What is the angle at which the object with mass 7m is scattered?

____ degrees counterclockwise from the +x-axis
