No, units problem, km/h must be converted.
250 km/h * 1000 m/km * (1/ 3600) h/s =250/3.6 meters/second
Find the force acting on a 12,500 kg F4 Phantom jet in the following situations (you will need to find the acceleration first) :
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.
