Problem
A stationary icy meteoroid with total mass 12kg breaks apart in the vacuum of space into three fragments whose motion is confined to a horizontal plane. Immediately after the breakup:
• Fragment A has mass 4kg and moves due east at 6.0ms−1.
• Fragment B has mass 3kg and moves due north at 8.0ms−1.
(a) Determine the x- and y-components of the velocity of Fragment C (mass 5kg) immediately after the breakup.
(b) Using your results from part (a), calculate the magnitude and compass direction of the velocity of Fragment C.
(c) Compute the total kinetic energy of all three fragments just after the breakup.
