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 4.10 m/s2 until it reaches an altitude of 1190 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) For what time interval is the rocket in motion above the ground? (b) What is its maximum altitude? km(c) What is its velocity just before it hits the ground?
A missile silo is used to launch test rockets vertically upward out of the silo, giving the rocket an initial speed of 79.0 m/s at ground level. As the rocket clears the silo, the engines fire, and the rocket accelerates upward at 4.20 m/s2 until it reaches an altitude of 1,080 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. Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)
(a)
Determine the velocity of the rocket (in m/s) at the end of the engine burn time and also the burn time (in s). (For the velocity, indicate the direction with the sign of your answer.)
velocity at end of engine burn timev= m/sengine burn timet= s
(b)
Determine the maximum altitude of the rocket (in m) and the total time (in s) for the rocket to reach this…
A rocket is fired vertically upward with an initial velocity of 80 m/s at the ground level. Its engine then fires and it accelerated at 4m/s2 until it reaches an altitude of 1200m. At that point, the engine fail and the rocket goes into free fall. Disregard air resistance. How long was the rocket above the ground?

- An Osprey can fly horizontally (not diving) at a maximum speed of 70.0 km/hr. The bird takes off from rest at the edge of a cliff, heading east, and accelerates at a rate of 1.21 m/s2. The osprey can decelerate at higher rate of 2.43 m/s2. The Osprey can reach top speeds of about 84 mph. When doing so, it does not flap its wings. Rather, it relies on its gravitational force to accelerate it downwards. a. Assuming that it starts from rest, and assuming that drag forces are slim, how long will it take for the osprey to reach its top speed? b. How far does it travel during this time? c. Near the top speed, drag forces become important, and in fact the terminal velocity is determined by the drag force.

Its acceleration for the first three seconds is a(t)=96t at which time the fuel is exhausted and it becomes a freely "falling" body. 19 seconds later, the rocket's parachute opens, and the (downward) velocity slows linearly to -16 ft/s in 5 s. The rocket then "floats" to the ground at that rate. At what time does the rocket reach its maximum height? And what is that height?arrow_forwardA model rocket is initially a height of H = 2.00 m above the ground. At t = 0, it is released from rest and has its engines ignited. Its engines generate an acceleration in the positive y-direction which changes with time of magnitude ßt, where = 18.00 m/s³. This acceleration doesn't include the effects of gravity.
