Given,

Force acting on the rider = 100 N

Acceleration = 2.8 m/s²

To find,

The mass of the rider.

Solution,

Let m is the mass of the rider. Using Newton second law of motion as follows :

F = ma

[tex]m=\dfrac{F}{a}\\\\m=\dfrac{100}{2.8}\\\\=35.71\ kg[/tex]

So, the mass of the rider is 35.71 kg.
