Question

In the "Dirty Harry" movies, the title character (played by Clint Eastwood) was famous for carrying a Smith&Wesson .44 magnum revolver, allegedly "the most powerful handgun in the world". For this problem, assume that Harry's gun carries six bullets, each with a mass of 15 g, and that the bullets exit the gun at a speed of 500 m/s.
(a) Dirty Harry is attempting to apprehend a dangerous criminal in a cheese shop, but one of his shots goes astray and hits a 1.7 kg block of Gouda, becoming lodged inside the dense hunk of cheese. What is the magnitude of the Gouda's velocity after being struck by the bullet?
m/s

Explanation / Answer

by conservation of momentum mass of bullet *velocity of bullet=mass of gouda*velocity of gouda (15/1000)*500=1.7*velocity of gouda 4.41m/s
