A ball moving on a horizontal frictionless plane hits an identical ball at rest with a velocity of `0.5m//s`. If the collision is elastic, calculate the speed imparted to the target ball, if the speed of projectile  after the collision is `30cm//s`. Show that the two balls will move at right angles to eachother, after the collision.
