Find graphically, the mass of the body that reaches a velocity of $35\frac{m}{s}$ after $4$ seconds of flight. To do so$,$ plot the velocity function given above with respect to mass $m$ with value of $t=4s.$ By visually inspecting the plot detect what value of $m$ makes the velocity reach the value of $35\frac{m}{s}.$ Finally, print your findings with a print statement.
