A can of sardines is made to move along an x axis from x = 0.46 m to x = 1.20 m by a force with a magnitude given by F = exp(-5x), with x in meters and F in newtons. (Here exp is the exponential function.) How much work is done on the can by the force?
A projectile (mass = m) is launched vertically upward with initial velocity v. When it has reached a height h above its launch position, it is still moving upward, but at that moment it explodes into two pieces. For what time interval was this impa..
