A model rocket blasts off and moves upward with an acceleration of 12 m/s2 until it reaches a height of 29 m, at which point its engine shuts off and it continues its flight in free fall. Use g = 9.81 m/s2.

a. What is the maximum height attained by the rockets?

b. What is the speed of the rocket just before it hits the ground?

c. What is the total duration of the rocket's flight?

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 81.0 m/s at ground level. The engines then fire, and the rocket accelerates upward at 3.90 m/s2 until it reaches an altitude of 1020 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of ?9.80 m/s2. (You will need to consider the motion while the engine is operating and the free-fall motion separately.) (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

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 rocket is launched from rest and moves in a straight line at 72.0° above the horizontal with a constant acceleration of 47.8 m/s2. After 31.7 s the engines shut off and the rocket follows a parabolic trajectory back to the ground (Assume that the acceleration due to gravity is 9.81 m/s2). What is the time of flight from launch to impact? What is the maximum altitude reached? What is the horizontal distance reached?
