Q5 On a pool table, the white ball of mass m,yhie traveling with velocity Vwhite strikes a green ball of mass mgren which is standing still. The green ball takes of while the white ball now stands still. Given that mw hate = mgrven show by conservation of momentum, i.e. Pwhite Pgreenwhie+ Pgre that the green ball now has the velocity of the white ball

Explanation / Answer

Q5:

mwhite = mass of white ball

vwi = initial velocity of white ball before collision = vwhite

vwf = final velocity of white ball after collision = 0

mgreen = mass of green ball

vgi = initial velocity of green ball before collision = 0

vgf = final velocity of green ball after collision = ?

Using conservation of momentum

mwhite vwi + mgreen vgi = mwhite vwf + mgreen vgf

mwhite vwhite + mgreen (0) = mwhite (0) + mgreen vgf

mwhite vwhite = mgreen vgf

since  mwhite = mgreen

hence vwhite = vgf
