You are given the equation used to solve a problem: $(0\mathrm{.}30$kg$)(40$m$/$s$)(0\mathrm{.}30$kg$)(30$m$/$s$)=12(1300$N$)$t$(0\mathrm{.}30$kg$)(40$m$/$s$)(0\mathrm{.}30$kg$)(30$m$/$s$)=12(1300$N$)$t$.$

Part A

Write a realistic problem for which this is the correct equation.

A $0\mathrm{.}30$ kgkg ball traveling to the left at $30$ m$/$sm$/$s is batted back to the right at $40$ m$/$sm$/$s$.$ The force curve for the force of the bat on the ball can be modeled as a rectangle with an average force of $1300$ NN$.$ How long is the ball in contact with the bat?A $0\mathrm{.}30$ kgkg ball traveling to the left at $30$ m$/$sm$/$s is batted back to the right at $40$ m$/$sm$/$s$.$ The force curve for the force of the bat on the ball can be modeled as a triangle with an average force of $1300$ NN$.$ How long is the ball in contact with the bat?A $0\mathrm{.}30$ kgkg ball traveling to the left at $30$ m$/$sm$/$s is batted back to the right at $40$ m$/$sm$/$s$.$ The force curve for the force of the bat on the ball can be modeled as a triangle with a maximum force of $1300$ NN$.$ How long is the ball in contact with the bat?A $0\mathrm{.}30$ kgkg ball traveling to the left at $30$ m$/$sm$/$s is batted back to the right at $40$ m$/$sm$/$s$.$ The force curve for the force of the bat on the ball can be modeled as a rectangle with a maximum force of $1300$ NN$.$ How long is the ball in contact with the bat?
