No, units problem, km/h must be converted.
250 km/h * 1000 m/km * (1/ 3600) h/s =250/3.6 meters/second
1. It is catapulted from rest to 250 km/hr in 2.2 seconds.
Acceleration: (250/2.2) / 2.2 = 51.6
F = 12,500 * 51.6 = 645 645N
Is my answer correct? I appreciate if someone can help me with this.
250 km/h * 1000 m/km * (1/ 3600) h/s =250/3.6 meters/second
However, the formula you used to calculate the force is incorrect. The correct formula to calculate force is:
Force = mass * acceleration
So the correct calculation would be:
Force = 12,500 kg * 113.64 m/s² = 1,420,500 N
Therefore, the force acting on the 12,500 kg F4 Phantom jet when it is catapulted from rest to 250 km/hr in 2.2 seconds is approximately 1,420,500 Newtons.
Please note that for simplicity, I have not considered any external factors such as air resistance or friction in this calculation.
Next, you have multiplied the mass of the jet (12,500 kg) by the calculated acceleration (51.6 m/s^2) to find the force acting on the jet. This is done using the formula force = mass * acceleration.
Therefore, the force acting on the F4 Phantom jet is 645,645 Newtons.
