Fuel is consumes at the rate of 100kg/s in a rocket. The exhaust gases are ejected at speed of 4.5×104m/s. What is the thrust experienced by the rocket? a) 3.19×106N b) 4.5N c) 3.19N

1. A new design of Saturn 13 rocket with mass 1.03 x106 kg has a propulsion engine that can eject gases at a constant speed of 245.03 m/s (vGas) by burning fuel at a rate of 4.15  x10 5  kg/s (dmdT). In full tank, the rocket can carry a fuel of mass 44.46  x10 6  kg. If this design exceeds the velocity of 11,200 m/s it can can successfully escape Earth's gravity. Determine if this is so. Find its maximum velocity (velyZ). (Pitch Angle = 0) 2. A 0.16-kg toy car is initially moving at 1.6 m/s. Since the battery is losing power, the toy car has slowed down to 0.3 m/s. Calculate the impulse of the toy car. Input the numerical value only; do not include the units.

(COLLAB) A new design of Saturn 15 rocket with mass 1.55 x106 kg has a propulsion engine that can eject gases at a constant speed of 366.1 m/s (vGas) by burning fuel at a rate of 4.67  x10 5  kg/s (dmdT). In full tank, the rocket can carry a fuel of mass 41.42  x10 6  kg. If this design exceeds the velocity of 11,200 m/s it can successfully escape Earth's gravity. Determine if this is so. Find its maximum velocity (velyZ) in a PhysLab virtual simulation. (Pitch Angle = 0)
