a person is riding a bike and accelerating at 2.8 m/5 2 eith a force of 100 n

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.
