Can anyone please help me with this?

Find the force acting on a 12,500 kg F4 Phantom jet in the following situations:
1. It is catapulted from rest to 250 km/hr in 2.2 seconds.

How can I find the acceleration for this problem??

  1. first 250 km/hr = 250,000 meters / 3600 seconds = V

    acceleration = rate of change of velocity
    = change in V / change in time = (250,000/3600) / 2.2 meters/ second^2

  2. vfinal=acceleration*time

    change km/hr to m/s
