Given that the force applied on the mystery object is, F = 300 N and the maximum speed, v = 40 m/s, and the time is taken, t = 7.15 s

If the initial speed, u = 0, then the acceleration will be

[tex]\begin{gathered} a=\frac{v-u}{t} \\ =\frac{40-0}{7.15} \\ =5.594m/s^2 \end{gathered}[/tex]

The mass, m of the mystery object can be calculated using Newton's second law of motion,

[tex]\begin{gathered} m=\frac{F}{a} \\ =53.628\text{ kg} \end{gathered}[/tex]

Thus, the mass of the mystery object is 53.628 kg.
