First, we need to convert the final velocity from km/hr to m/s because the mass is given in kg and we want our force in Newtons (which is in kg*m/s²).

1 km/hr = 1000 m/3600 s = 0.27778 m/s

So, vf = 1500 km/hr = 1500 * 0.27778 m/s = 416.67 m/s

Next, we use the formula for acceleration which is final velocity minus initial velocity divided by time. Since the rocket starts from rest, the initial velocity is 0.

a = (vf - vi) / tf = (416.67 m/s - 0 m/s) / 2 s = 208.33 m/s²

Finally, we use the formula for force which is mass times acceleration.

F = m * a = 550 kg * 208.33 m/s² = 114583.33 N

So, the magnitude of the required net force is approximately 115,000 N (to 3 significant figures).
