13. A vertically launched rocket expels the gases at a constant velocity of 5 x 10^-2 m or Kg s-1, where mo is its initial mass. The exhaust velocity of the gases with respect to the rocket is 5 x 10 ^ 2 m / s. Find the speed and height of the rocket after 10 s.

A rocket is launched vertically up with no initial velocity. Propulsion is provided by the ejection of mass with constant velocity of ejection u = 66.0 m/s relative to the rocket and at a constant rate so determined that the initial acceleration is zero. The mass of fuel that can be ejected is 55.0% of the total mass at launch. Assuming constant gravitational acceleration, how long does it take the rocket to achieve maximum upward acceleration?

A rocket accelerates by burning its onboard fuel, so its mass decreases with time. Suppose the initial mass of the rocket at liftoff (including its fuel) is m, the fuel is consumed at rate r, and the exhaust gases are ejected with constant velocity ve (relative to the rocket). A model for the velocity of the rocket at time t is given by the equation v(t) = −gt − ve ln m − rt m where g is the acceleration...

The graph gives the vertical velocity of the rocket versus time after it is launched at t = 0.0 s. The rocket starts climbing with a constant speed of 23 m/s. At t = 2.0 s the rocket engine shuts off and the rocket is then in free-fall motion and falls back to the ground. What maximum height above the ground does the rocket reach?

If a 2500 kg rocket is launched from the Earth's surface at a speed of 5 km/s, how high can it reach before it returns back down?(Mass of Earth is 5.98 x 10^24kg, radius is 6.38 x 10^6m)? Find the gravitational accelerations at this highest point. This would be the initial downward acceleration of the rocket.

A small rocket is launched vertically from the ground and experiences an upward acceleration of 5 m/s2. The engine burns out after 4 seconds and the rocket moves under the influence of gravity until it returns to the ground. You may neglect air resistance. Draw the position, velocity, and acceleration vs. time curves for the entire flight from t=0 to t=9.5 s. Take the +y axis to be upward. A) what is the Position vs. Time graph? B) What is...

A 2400-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 1.90 m/s2 and 1.20 s later an upward velocity of 1.50 m/s . Part A) Determine A....

Carlon launched a toy rocket vertically from ground level (y=0m, time=0s). The rocket's engine provides constant acceleration during the burn phase. At the instant of engine burnout the rocket has risen 89m. The rocket continues to rise in unpowered flight, reaches mex height of 232m, and then falls back to the ground. What is the rocket engine upward acceleration closest too? A. 12.1m/s B. 22.3 m/s C 15.8 m/s
