Final answer:
Maintaining more distance behind a motorcycle than other vehicles is safer due to visibility and stopping distance considerations. For physics calculations involving motorcycles, the force exerted for acceleration can be determined using Newton's Second Law, accounting for mass, acceleration, and resistive forces.
Step-by-step explanation:
The distance to maintain behind a motorcycle should be more than other vehicles because motorcycles can be harder to see and may stop more quickly than a car might. It is important for drivers to provide enough space to react safely to any potential sudden movements. When it comes to the physics related to motorcycles, calculations such as determining the magnitude of the force a motorcycle exerts for acceleration requires an understanding of Newton's Second Law of Motion. If a motorcycle with a rider has a mass of 245 kg, and it is capable of producing an acceleration of 3.50 m/s² while overcoming a total resistive force of 400 N, including friction and air resistance, the force can be calculated using the formula F = ma + resistive forces.
To calculate the force exerted backward on the ground by the motorcycle, we use:
F = (mass × acceleration) + resistive force
F = (245 kg × 3.50 m/s²) + 400 N
F = 857.5 N + 400 N
F = 1257.5 N
So, the magnitude of the force the motorcycle exerts backward on the ground is 1257.5 Newtons.
