Two smooth spheres of the same volume and of masses M, m (M bigger than m) are at rest on a smooth horizontal table. The sphere m is given an impulse I along the line of centers of two spheres and then impinges on the sphere M. If e is the coefficient of restitution between the two spheres. Prove that the loss of kinetic energy by impact is:

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
