Afarmer making grape juice fills a glass bottle to the brim and caps it tightly. the juice expands more than the glass when it warms up, in such a way that the volume increases by 0.2% (that is, δv / v0 = 2×10−3 ) relative to the space available. calculate the magnitude of the normal force exerted by the juice per square centimeter if its bulk modulus is 1.8×109 n/m2 , assuming the bottle does not break.

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
