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)...

Agriculture will need to become more efficient than ever and producing food for the projected population of 9 to 10 billion by 2050. Imagine you're in charge of a large plant breeding program. You are tasked with identifying the most important qualities or traits for improvement in the coming decades. Which traits do you choose and why?

A 25kg rocket stays on a launch pad at rest when it's engines fire and a constant thrust pushes the rocket upward with a constant 500N thrust force. The engines fire for the first 20 m and then abruptly cut off. The maximum height of the rocket is 35m. How much energy does air resistance take away from the rocket?

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?

An airplane is flying at an altitude of 10 km at 120 m/s. Its jet engines, which for now can be approximated as a converging duct, have an inlet diameter of 1.5m and an exit diameter of 0.3m. The exit of the engine has a temperature altitude of 11 km, and pressure altitude of 10.5 km. a. Is the flow incompressible or compressible? How do you know? b. What is the velocity at the engine exit?

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!

Suppose a rocket ship at position x=0 begins firing its engines at time t=0, causing it to increase its speed with a constant acceleration a0. At t=t0, the engines are turned off. Assuming that the rocket always moves in a straight line (x-direction), find the expressions for the velocity and position of the rocket for 0<t<t0 and t>t0. Draw graphs of velocity vs. time and position vs. time.

Small rocket engines, such as model rockets, contain KClO3 to provide oxygen for the combustion reaction that fuels the rocket motor. The relevant reaction for KClO3 is: 2 KClO3(s) → 2 KCl(s) + 3 O2(g). If 141.6 grams of solid KClO3 are burned in one of these rocket motors, how many liters of gaseous O2 will be produced at 1.18 atm of pressure and 538oC?
