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? 841 The impulse ims At = 0.04 s F Fmax
