A 100-gram steel marble traveling at 5 m/s [Right] collides with a target
sphere at rest. The magnitude of the force between the marble and the
sphere is given by F = √2kFt-k²² where Fmax = 10.0 N and the
constant k = 500 N/s. The force is graphed vs. time at right. The curve
forms a semicircle.
83) The collision begins at time t = 0 when the force between the marble on the
sphere increases from zero. The collision ends when the force decreases to
zero again. How long does the collision last?
