A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. What is the initial acceleration of the rocket, assuming you can neglect air resistance? 7.6 m/s² 15.2 m/s² 50.0 m/s² 25.0 m/s² QUESTION 4 Same rocket as in the previous question. After the rocket has been in flight for a while, having burned and exhausted 80,000 kg of propellant, its acceleration has reached 25.0 m/s2. All this while the thrust has been constant at 5.00 x 106 N. What is the magnitude of the drag force (that is, the resistance from the air) at this point? Note that at this point the rocket's altitude is still low, so you can still take gravity to be g = 9.81 m/s² 3.00 x 106 N 5.00 x 106 N 1.18 x 106 N 8.23 x 105 N
