Two bicyclists are accelerating forward at the same rate. The net force on both bikers is in the forward direction, but the net force on Biker 1 is greater
than on Biker 2. Which statement describes the mass of the bikers?
A. Biker 1 has more mass than Biker 2.
B. The mass of Biker 2 is greater than the mass of Biker 1.
C. The bikers have the same mass.
O
D. The masses of both bikers are constantly changing.

A. Biker 1 has more mass than Biker 2

Explanation:

From the given problem;

    Both bikers are moving in the same direction;

     Both bikers have the same acceleration

     Net force on biker 1 is greater than the net force on biker 2

Now, the mass of the bikers  = ?

From Newton's second law of motion, the force on a body is a product of its mass and acceleration;

     Force  = mass x acceleration

Since both Bikers are moving with the same acceleration, this quantity is constant.

So, the mass of Biker 1 must be greater than mass of Biker 2 to attain this constant acceleration.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
