A model rocket is launched straight upward with an initial speed of 59.0 m/s. It accelerates with a constant upward acceleration of 2.50 m/s2 until its engines stop at an altitude of 160 m.

(a) What can you say about the motion of the rocket after its engines stop?



(b) What is the maximum height reached by the rocket?



(c) How long after liftoff does the rocket reach its maximum height?


(d) How long is the rocket in the air?

Create this in MATHLAB A model rocket is launched straight up with a speed of 45.0 m/s and maintains an upward acceleration, including air and gravitational resistance. the acceleration of the rocket is  800m/s2 for 10s at which point the engines run out of fuel. The rocket continues upward to its maximum height and falls back towards the Earth. After falling for 7.65m, from its maximum height, what is the decay of the rocket reaching its starting point.

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 34.3 m/s2 . The acceleration period lasts for time 8.00 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 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)...

A rocket is launched at an angle of 53.0° above the horizontal with an initial speed of 104 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 32.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile.(a) Find the maximum altitude reached by the rocket.(b) Find its total time of flight.(c) Find its horizontal range. Please solve with steps thanks!

1460 kg weather rocket accelerates upward at 12 m/s2. It explodes 2.0 s after liftoff and breaks into two fragments, one twice as massive as the other. Photos reveal that the lighter fragment traveled straight up and reached a maximum height of 530 m. What were the speed and direction of the heavier fragment just after the explosion?

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?
