8. A rocket is launched vertically upwards and experiences an acceleration of 4x10 m.s2 for 8...
A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...
A rocket is launched vertically from ground with a constant acceleration. If the rocket emits a burst of sound every five seconds after launching, find the intensity level difference observed at the launching site from the first burst and the second burst of sound.
a.) The acceleration of a rocket fired vertically upwards t seconds after launch is 20+2t ms−2 (as a rocket burns fuel it becomes lighter, so accelerates more quickly). What is the second order differential equation for the height of the rocket. h′′= b.) What is the general solution? (Please use A as the first constant of integration and B as the second): General solution: h = c.) Use the fact that at t = 0 the rocket was on the...
An object is launched vertically upwards from the side of a building at a height of 100 m above the ground. It takes a total of 3.07 seconds to return to the same height of 100 m. With what speed was it launched in m/s? Hint: find the time it takes to reach the maximum vertical displacement first.
an object propelled upwards with an acceleration of 2.0 m / s ^ 2 is launched from rest. After 6 seconds the fuel runs out. Determine the speed at this time and the maximum height at which it reaches.
A. If a rocket was launched vertically from rest with an acceleration of 15 m/s² for 10 seconds, what height did the rocket reach and how long was the rocket in the air?
Two bodies are launched from the ground vertically upwards with an initial velocity of 400 [m / s] and with a time interval between each release of 20 [s]. Determine a) The time it takes to reach the maximum height. b) The maximum height reached c) The meeting time of the bodies. d) The height at which they are found e) The speed of each body at the moment of the encounter F) The speed just before hitting the ground.
2. A rocket is launched directly upwards at sea-level and a viewer watches from 6500 meters away, also at sea-level. After some time, the viewer was able to measure the angle between the ground and the rocket as 75°. Use a sum or difference identity to help determine the height of the rocket at that time. Your answer should not have any trigonometric expressions or radicals in denominators 2. A rocket is launched directly upwards at sea-level and a viewer...
a rocket is shot upward. its motor burns for ten seconds giving an acceleration of 15m/s/s, but after it burns it is in free fall. draw the velocity v. time graph, acceleration v. time graph and the position v. time graph. how high above the ground is the rocket once the motor runs out, how fast is the rocket traveling once its motor runs out, how fast is the rocket traveling when it reaches its maximum height, and what is...
A rocket rises vertically, from rest, with an acceleration of 3.4 m/s2 until it runs out of fuel at an altitude of 1500 m . After this point, its acceleration is that of gravity, downward. A) What is the velocity of the rocket when it runs out of fuel? B) How long does it take to reach this point? C) What maximum altitude does the rocket reach? D) How much time (total) does it take to reach maximum altitude? E)...
