At launch a rocket ship weighs 4.5 million pounds. When it is launched from rest, it takes 8.00 s to reach 163 km/h ; at the end of the first 1.00 min, its speed is 1630 km/h.
A. What is the average acceleration (in m/s2) of the rocket during the first 8.00 s?
B. What is the average acceleration (in m/s2) of the rocket between 8.00 s and the end of the first 1.00 min?
C. Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the rocket travel during the first 8.00 s? Express your answer with the appropriate units.
D. Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the rocket travel during the interval from 8.00s to 1.00 min? Express your answer with the appropriate units.

1. A rocket accelerates upward from rest during the first stage with a constant acceleration of a1 = 95.0 m/s2 for t1 = 30.0 s. The first stage then detaches and the second stage fires, providing a constant acceleration of a2 = 50.0 m/s2 for t2 = 60.0 s. (a) What is the total distance traveled by the rocket during both stages? (b) What is the speed of the rocket after the second stage burn?

During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad and accelerates upward at a steady 3.45 m/s2 . When it is 235 m above the launch pad, it discards a used fuel canister by simply disconnecting it. Once it is disconnected, the only force acting on the canister is gravity (air resistance can be ignored). How high is the rocket when the canister hits the launch pad, assuming that the rocket does...

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 6600 m.You can ignore any effects of air resistance. What was the rocket's acceleration during the first 16 s? Express your answer with the appropriate units.

During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad and accelerates upward at a steady 3.15 m/s2 . When it is 260 m above the launch pad, it discards a used fuel canister by simply disconnecting it. Once it is disconnected, the only force acting on the canister is gravity (air resistance can be ignored). A) How high is the rocket when the canister hits the launch pad, assuming that the rocket...

1a) A rocket ship in deep space accelerates from rest at a constant rate of 9.6 m/s2, which is close to the acceleration of gravity on earth and would give the sensation of near-normal gravity during the voyage.How long will it take the ship to reach 0.103c (c = speed of light, 3.0 x 108 m/s)? Your answer should be in s, but enter only the numerical part in the box. You can use exponential notation, if desired. For example,...

A rocket is launched vertically from rest, it reaches an altitude of 5.2km after 16s of constant acceleration. What was the magnitude of the acceleration of the rocket? How many times larger than the acceleration due to gravity is this? Is this rocket safe for human passengers? Calculate the error in acceleration (equation 2.1) assuming vo=0 m/s, Δx ± δx and t ± δt.

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?
