Problem 4: During a snowball fight two balls with respective masses of 1.6 and 0.4 kg
are thrown in such a manner that they meet with their velocities forming a 30° angle.
After the collision, the two snowballs combine to form a single mass. The speed of each
snowball just before the collision is 15 m/s.
(a) The speed of the combined snowball immediately after collision is
(b) The kinetic energy of the combined snowball (with mass 2 kg) is
