13. ball of clay with mass 0.100 kg directly dropped from 1.50 m above the ground. (a) what is the
speed of the clay ball just before it hits the ground? (b) if the clay ball stick to the floor after hitting
the ground in 0.00250 s, calculate the force on the clay by the floor. (ignore the gravity) (c) what is
the force created on the ground by the clay ball? (ignore the gravity) (d) why is the force of gravity
not that important for part b and c? (e) calculate the impulse on the ball (f) calculate the impulse on
the ground.
