Acareful photographic survey of jupiter’s moon io by the spacecraft voyager 1 showed active volcanoes spewing liquid sulfur to heights of 70 km above the surface of this moon. if the value of g on io is 2.0 m/s2 , estimate the speed with which the liquid sulfur left the volcano.

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.
