Answer:
A. Biker 1 has more mass than Biker 2
Step-by-step 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.
