A swimmer weighs 198lbs. He swam 100m. What is his speed, the acceleration and momentum
To determine the swimmer's speed, we need to know the time it took the swimmer to swim 100m.
To calculate the acceleration, we need additional information such as the initial and final velocity or the time it took to reach a certain velocity. Without this information, we cannot determine the acceleration of the swimmer.
The momentum of an object is calculated using the formula: momentum = mass * velocity. Since the swimmer weighs 198lbs, we need to convert this weight to mass in order to calculate momentum.
1 pound (lb) is equal to 0.453592 kilograms (kg). Therefore, the mass of the swimmer can be calculated as follows:
mass = weight / 2.20462
mass = 198lbs / 2.20462 = 89.811kg
If we have the time taken to swim 100m, we can calculate the speed using the formula: speed = distance / time.
Without the time or additional information, it is not possible to calculate the speed, acceleration, or momentum of the swimmer accurately.
