A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 49.0 m/s2 . The acceleration period lasts for time 7.00 s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2 .

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 29.4m/s2 . The acceleration period lasts for time 9.00s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2 . Write your answer numerically in units of meters.

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 53.9 m/s^2. The acceleration period lasts for time 5.00 s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height y_max reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s^2. Write your answer numerically in units of meters.

An astronaut in his space suit and with a propulsion unit (empty of its gas propellant) strapped to his back has a mass of 146 kg. The astronaut begins a space walk at rest, with a completely filled propulsion unit. During the space walk, the unit ejects some gas with a velocity of 32 m/s. as a result, the astronaut recoils with a velocity of .39 m/s. After the gas is ejected, the mass of the astronaut (now wearing a...
A rocket, initially at rest on the ground, accelerates straight upward with constant net acceleration, from time t=0 until, at which time the fuel is exhausted
A rocket, initially at rest on the ground, accelerates straight upward with constant net acceleration, from time t=0 until, at which time the fuel is exhausted. Neglect air resistance and assume that the rocket stays close enough to the ground that the acceleration due to gravity (after the rocket engine stops) is given by g. a) Find the maximum height, h, that the rocket reaches above the ground. b) Find the total time of flight, that the rocket is in...

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...

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...

During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad and accelerates upward at a steady 3.20 m/s2 . When it is 250 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). Part A How high is the rocket when the canister hits the launch pad, assuming that the...

(8%) Problem 11: A student launches a small rocket which starts from rest at ground level. At a height of h- 1.85 km the rocket reaches a speed of ve 395 m/s. At that height the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward in this problem.
