A rocket that is in deep space and initially at rest relative to an inertial reference frame has a mass of 2.80 105 kg, of which 1.92 105 kg is fuel. The rocket engine is then fired for 250 s while fuel is consumed at the rate of 480 kg/s. The speed of the exhaust product relative to the rocket is 3.21 km/s. (a) What is the rocket's thrust? N (b) What is the mass of the rocket after the...

A rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 85.2 x 105 kg, of which 18.3 x 105 kg is fuel. The rocket engine is then fired for 170 s, during which fuel is consumed at the rate of 360 kg/s. The speed of the exhaust products relative to the rocket is 2.60 km/s. (a) What is the rocket's thrust? After the 170 s firing, what are (b)...

A small sounding rocket has an initial mass of M=3200kg (80% of which is fuel) and burns fuel at a rate of 20 kg/s. The exhaust velocity of the gas ejected from the rocket is Uex=2000m/s. a. Find the thrust of the rocket motor. b. Find the time until burnout. c. Find the speed of the rocket at burnout assuming that the rocket moves straight up and stays close enough to Earth's surface that the gravitational acceleration is always g=9.81m/s^2

A Saturn-V Rocket has a total mass of 3.00 times 10^6 kg when fully fueled. The first stage of rocket propulsion burns 2.27 times 10^6 kg of fuel in 150 s, providing a thrust of 3.402 times 10^7 N, as the rocket is lifted against Earth's gravity. a) Find the rate at which fuel is burned during this first-stage propulsion, assuming a steady rate of fuel consumption. b) Find the exhaust speed of the fuel as it is ejected from...

1.) You are in a spaceship at rest in deep space, outside the influence of any gravity. Without fuel, your vessel has a mass of 5,750 kg and its rocket engine expels exhaust at a speed of 8,250 m/s. You want to travel to an outpost that is quite far away, and you decide to accelerate to a speed of 12,500 m/s, coast for some time, and then slow down to a stop. A) What is the minimum mass of...

1. 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. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b) After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...

1. Calculate the primary NAAQS concentration limit for 502 in units of ug/m' at standard temperature and pressure (STP:T - 25*C, P = 1 atm). 2. Fuel X9-6000 is 95.8% efficient in an airplane engine. The unburned fuel leaves as VOCS in the exhaust. For each kg of fuel X9-6000 (Molecular Weight, MW-98), the engine exhausts 20 kg of gases (MW = 28 g/mol). What is the fraction of VOCs in the exhaust (ppm)? ncinerator burns 30 tonnes of plastic...
