A $240$g volleyball approaches Zeenya Latture with a speed of $3\mathrm{.}8\frac{}{}$m/s. Zeenya bumps the ball, giving it a speed of $2\mathrm{.}4\frac{}{}$m/s away from her. What average force did she apply if the interaction time between her hands and the ball is $0\mathrm{.}025s?$

a$)$ Draw a picture of the situation and establish directions $($and signs$)$ for the speeds.

b$)$ Solve your problem for both the magnitude and direction of the force $($possible directions are toward Zeenya or away from. Zeenya$).$
