Final answer:
Jimmy weighs approximately 637.65 Newtons on Earth, which can be calculated by multiplying his mass (65kg) by Earth's gravitational acceleration (9.81 m/s²). Weight is a force measured in Newtons in the SI system.
Step-by-step explanation:
To determine how much Jimmy weighs on Earth with a mass of 65kg, we need to apply the concept of weight as the force due to gravity on an object. Weight can be calculated using the formula:
Weight (W) = Mass (m) × Gravitational Acceleration (g)
On Earth, the average gravitational acceleration (g) is approximately 9.81 meters per second squared (m/s²). Therefore, to calculate Jimmy's weight on Earth, we would multiply his mass by the gravitational acceleration:
W = 65 kg × 9.81 m/s²
This calculation results in a weight of:
W = 637.65 Newtons (N)
Remember that weight is a measure of force and is expressed in Newtons in the SI system. If you wish to convert this weight to the more common unit of pounds, you would use the conversion factor that 1 Newton is approximately equal to 0.225 pounds.
