5. Rocket guidance A space probe with mass 5180 kg is traveling beyond Saturn with a velocity of 115 m/s. When it is time to alter its course by 30.0°, the probe's thruster jets are fired briefly in a direction perpendicular to its original motion. If the thruster gases are expelled at a speed of 1750 m/s, how much mass must be expelled during the course correction?

The lunar model ascent vehicle was a rocket that lifted off from the surface of the Moon. The Moon's mass and radius are, respectively M = 7.33 x 1022 kg, and Rm = 1.73 x 106m. The rocket expelled exhaust gases at Ve = 3.0 x 103 m/s. Its initial mass, including fuel, was 4800 kg, and it burned fuel at a rate Am/At= 10 kg/s. Calculate the initial acceleration of the rocket taking off from the surface of the...

4: Suppose the mass of a
rocket just as it runs out of fuel is 75550-kg, and its exhaust
speed is 2.7 × 103 m/s.
Calculate
the maximum rate, in kilograms per second, at which the rocket can
expel gases, if its acceleration cannot exceed seven times that of
the gravitational acceleration on the surface of the Earth. Assume
the gravitational force on the rocket is negligible.

Boxing gloves are padded to lessen the force of a blow. (a) Calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) Calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only...

A rocket in outer space has a payload of 5055.6 kg and 1.542 . 105 kg of fuel. The rocket can expel propellant at a speed of 5.580 km/s. Assume that the rocket starts from rest, accelerates to its final velocity, and then begins its trip. How long will it take the rocket to travel a distance of 3.82. 103 km (approximately the distance between Earth and Moon)? Question A fire hose 4.54 cm in diameter is capable of spraying...
