Final answer:
The acceleration of Juan and his bicycle, with a combined mass of 80 kg and acted on by a 30 N net force, is calculated to be 0.375 m/s² using Newton's second law of motion, F = ma.
Step-by-step explanation:
The question given by the student asks about calculating the acceleration of Juan and his bicycle when a net force of 30 Newtons is acting on them. This problem can be solved using Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object times its acceleration (F = ma). To find the acceleration, we rearrange the formula to a = F/m.
In this case, Juan and his bicycle have a combined mass of 80 kg, and the net force acting on them is 30 N. Using the formula, we calculate the acceleration as:
a = F/m = 30 N / 80 kg = 0.375 m/s²
Therefore, the acceleration of Juan and his bicycle at that moment is 0.375 meters per second squared (0.375 m/s²).
