Final answer:
Biker 2, with more mass, will experience a greater net force than Biker 1 because of Newton's second law of motion.
Step-by-step explanation:
In this scenario, both bikers are accelerating forward at the same rate. Biker 1 has less mass than biker 2. According to Newton's second law of motion, the net force acting on an object is directly proportional to its mass and acceleration. Since both bikers have the same acceleration but different masses, the biker with the greater mass (biker 2) will experience a greater net force.
