Final answer:
The mass of the motorcycle is 250 kg.
Step-by-step explanation:
To calculate the mass of the motorcycle, we can use the formula weight = mass * gravity. Given that the weight of the motorcycle is 2450 N and the acceleration due to gravity on Earth is 9.8 N/kg, we can rearrange the formula to solve for mass: mass = weight / gravity. Plugging in the values, we get: mass = 2450 N / 9.8 N/kg = 250 kg.
