Question

Can you help me determine the mass of the mystery object it’s #15The maximum speed is 40 m/s.

Answer 1

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

`\begin{gathered} a=(v-u)/(t) \\ =(40-0)/(7.15) \\ =5.594m/s^2 \end{gathered}`

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

`\begin{gathered} m=(F)/(a) \\ =53.628\text{ kg} \end{gathered}`

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