Chapter 2, Problem 28P

(a)

To determine

The net force acting on the ball while it is in motion.

(b)

To determine

The components of the ball’s momentum that will be changed by the net force on the ball.

(c)

To determine

The change in $x$ component of the ball’s momentum during its flight.

(d)

To determine

The change in $y$ component of the ball’s momentum during its flight.

(e)

To determine

The change in $z$ component of the ball’s momentum during its flight.

(f)

To determine

The reason why it is legitimate to use the expression for average $y$ component of velocity, $v_{\text{avg},y}=\left(v_{iy}+v_{fy}\right)/2$ to update the $y$ component of position.
