Answer:The net force acting on the bicycle is 688 N.Explanation:This can be calculated using the equation F = ma, where m is the mass of the bicycle and rider (85 kg) and a is acceleration (calculated from v/t, or 4.0 m/s divided by 8.0 seconds, which equals 0.5 m/s2). Therefore, F = 85 kg x 0.5 m/s2 = 688 N...
