Chapter 9, Problem 42P
(I) In a ballistic pendulum experiment, projectile 1 results in a maximum height h of the pendulum equal to 2.6 cm. A second projectile (of the same mass) causes the pendulum to swing twice as high, h2 = 5.2 cm. The second projectile was how many times faster than the first?

(III) A bullet of mass m = 0.0010 kg embeds itself in a
wooden block with mass M = 0.999 kg, which then com-
presses a spring (k = 140 N/m) by a distance x = 0.050 m
before coming to rest. The coefficient of kinetic friction
between the block and table is M = 0.50. (a) What is the
initial velocity (assumed horizontal) of the bullet? (b) What
fraction of the bullet's initial kinetic energy is dissipated
