- NASAs Saturn V rockets that launched astronauts to the moon were powered by the strongest rocket engine ever developed, providing 6.77 106 N of thrust while burning fuel at a rate of 2.63 103 kg/s. Calculate the engines exhaust speed.arrow_forwardA small puck is positioned on the top of a spherical surface. The puck is then released and gently nudged. At what polar angle will the puck fly offthe sphere? Hint: use an energy solution and the normal reaction at the point of fly-off. Keep in mind the friction of the sphere when modeling the normal reaction.arrow_forwardHow much fuel (in kg) would be needed for a 1,200-kg rocket (its mass with no fuel) to take off from Earth and reach 1,800 m/s in 20s?

- A kid at the junior high cafeteria wants to propel an empty milk carton along a lunch table by hitting it with a 3.0 g spit ball. If he wants the speed of the 20 g carton just after the spit ball hits it to be 0.30 m/s, at what speed should his spit ball hit the carton?arrow_forwardTwo balls collide and bounce off each other. The 500-g ball's initial velocity is 20 m/s while the 800-g ball has an initial velocity of 35 m/s. (a) What is the final velocity of the 500-g ball if the 800-g ball has a speed of 15 m/s after the collision?arrow_forwardHow much impulse is needed to stop a 25kg bowling ball rolling at 9m/s?arrow_forward
- During a spacewalk, Dmitri finds himself floating 3 m from his space station's airlock. He only has one minute of air left. He has one detachable 10 kg toolkit, which he can toss to propel himself toward safety. How fast will he need to move to reach the airlock before he runs out of air?arrow_forwardThe reason why I used 2g instead than g is that I have to cancel 2 "g" from the left side. Meaning I had to add 1/2g on the right side. Why are you instead adding only 1/g? Sorry, sometimes I get lost in the simple steps.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_forward
- A single-stage rocket of mass 308 metric tons (not including fuel) carries a payload of 3150 kg to low-Earth orbit. The exhaust speed of the rockets cryogenic propellant is 3.20 103 m/s. a. If the speed of the rocket as it enters orbit is 8.00 km/s, what is the mass of propellant used during the rockets burn? b. The rocket is redesigned to boost its exhaust speed by a factor of two. What is the mass of propellant used in the redesigned rocket to carry the same payload to low-Earth orbit? c. Because the exhaust speed of the redesigned rocket is increased by a factor of two, why is the fuel consumption of the redesigned rocket not exactly half that of the original rocket?arrow_forwardReview. The first stage of a Saturn V space vehicle consumed fuel and oxidizer at the rate of 150 104 kg/s with an exhaust speed of 2.60 101 m/s. (a) Calculate the thrust produced by this engine. (b) Find the acceleration the vehicle had just as it lifted off the launch pad on the Earth, taking the vehicles initial mass as 3.00 106 kg.arrow_forwardA model rocket engine has an average thrust of 5.26 N. It has an initial mass of 25.5 g, which includes fuel mass of 12.7 g. The duration of its burn is 1.90 s. (a) What is the average exhaust speed of the engine? (b) This engine is placed in a rocket body of mass 53.5 g. What is the final velocity of the rocket if it were to be fired from rest in outer space by an astronaut on a spacewalk? Assume the fuel burns at a constant rate.arrow_forward
