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 rocket is launched vertically from ground with a constant acceleration. If the rocket emits a...
8. A rocket is launched vertically upwards and experiences an acceleration of 4x10 m.s2 for 8 seconds. After this time, the engine is turned off and the rocket continues to rise to its maximum height. (a) Explain (using Newton's third law) why the rocket moves forward during the first 8 seconds. (2) (b) Calculate the velocity of the rocket 8 seconds after launching (2) (c) How long after launching does the rocket reach its maximum height? (2) (d) (2) At...
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?
Carlon launched a toy rocket vertically up from ground level (y = 0 m), at time t = 0.0 s. The rocket engine provides constant upward acceleration of 12.3 m/s2 during the burn phase. At the instant of engine burnout the rocket has risen to 89 m. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The maximum height reached by the rocket is closest to:
A rocket is launched straight up from the ground with constant acceleration. When it reaches a height of 240m, a bolt falls off the side of the rocket. The bolt hits the ground 6.0s later. A) How fast was the bolt (or rocket) going when it broke loose from the rocket? B) What was the rocket's acceleration? C) What was the maximum height that the bolt reached? Thanks.
Why is the answer B? 13) A toy rocket is launched vertically from ground level (y 0 m), at timet- 0.0 s. The rocket engine provides constant upward acceleration during the burn phase. At the instant of engine burnout, the rocket has risen to 72 m and acquired a velocity of 40 m/s. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The maximum height reached by the rocket is closest to:...
A rocket blasts off vertically from rest on the launch pad with a constant upward acceleration of 2.60 m/s2 .At 30.0 s after blastoff, the engines suddenly fail, and the rocket begins free fall. What is the height of the rocket when the engine fails? Find the magnitudes of the rocket's velocity and acceleration at its highest point. How long after it was launched will the rocket fall back to the launch pad?
A rocket, with an original mass of 20,000 kg, is launched vertically and expels 1000kg of mass every 20 seconds (take the average rocket recoil mass in applying momentum conservation). Determine the numerical value of the velocity of the rocket, after 2 10 second intervals, and also determine how far it has traveled at the end of that time.
A 1000 kg weather rocket is launched straight up.The rocket motor provides a constant acceleration for 16 s, then the motor stops. The rocket altitude 20 s after launch is 6200 m. You can ignore any effects of air resistance. What was the rocket's acceleration during the first 16s? What is the rocket's speed as it passes through acloud 6200 m above the ground?
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...
When it is 159 m above the ground, a rocket traveling vertically upward at a constant 8.30 m/s relative to the ground launches a secondary rocket at a speed of 12.4 m/s at an angle of 53.0 ∘ above the horizontal, both quantities being measured by an observer sitting in the rocket. Air resistance should be ignored. Part A : Just as the secondary rocket is launched, what are the horizontal and vertical components of its velocity relative to the...
