Concept explainers
You’re an engineer working on Ares I, NASA’s replacement for the space shuttles. Performance specs call for a first-stage rocket capable of accelerating a total mass of 630 Mg vertically from rest to 7200 km/h in 2.0 min. You’re asked to determine the required engine thrust (force) and the force exerted on a 75-kg astronaut during liftoff. What do you report?

- A rocket has a total mass of 1.17 105 kg and a burnout mass of 1.03 104 kg, including engines, shell and payload. The rocket blasts off from Earth and exhausts all its fuel in 4.17 min, burning the fuel at a steady rate with an exhaust velocity of ve= 4.89 103 m/s. (a) If air friction and gravity are neglected, what is the speed of the rocket at burnout? (b) What thrust does the engine develop at liftoff? (c) What is the initial acceleration of the rocket if gravity is not neglected?arrow_forwardHow much fuel would be needed for a 1000-kg rocket (this is its mass with no fuel) to take off from Earth and reach 1000 m/s in 30 s? The exhaust speed is 1000 m/s.arrow_forwardThe Merlin rocket engines developed by SpaceX can produce 7.70 ✕ 105 N of instantaneous thrust with an exhaust speed of 3.05 ✕ 103 m/s in vacuum. What mass of fuel does the engine burn each second to produce this thrust? (Enter your answer in kg/s.)arrow_forward
- A small rocket for gathering weather data has a mass of 30 kg and generates 1500 N of thrust. On a windy day, the wind exerts a 20 N horizontal force on the rocket. If the rocket is launched straight up, what is the shape of its trajectory, and by how much has it been deflected sideways when it reaches a height of 1.0 km? Because the rocket goes much higher than this, assume there’s no significant mass loss during the first 1.0 km of flight.arrow_forwardA rocket has a total mass of 1.01 105 kg and a burnout mass of 1.14 104 kg, including engines, shell and payload.

- There are two forces on the 1.19 kg box in the overhead view of the figure but only one is shown. For F1 = 15.7 N, a = 14.7 m/s2, and θ = 34.1°, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction.
