See attached handwritten document
A rocket rises vertically, from rest, with an acceleration of 3.2 m/s2 until it runs out of fuel at an altitude of 1300 m. After
this point, its acceleration is that of gravity, downward. (a) What is the velocity of the rocket when it runs out of fuel? (Assume up is positive.)
(b) How long does it take to reach this point?
(c) What maximum altitude does the rocket reach?
(d) How much time (total) does it take to reach maximum altitude?
(e) With what velocity does the rocket strike the Earth? (Assume up is positive.)
(f) How long (total) is it in the air?

Answer:
Part a)
Part b)
Explanation:
As the uniform sphere is rolling down the inclined plane then the net force on the sphere is given as
also we have torque equation on it
for pure rolling
now we have
now we have
now given that
so we have
Part b)
If the inclined plane is frictionless then the acceleration is given as
The tiny space invader and the new space station will have equal orbital speed.
<h3>The orbital speed of satellite </h3>
The orbital speed of satellite on Earth surface is given as;
where;
- V is the orbital speed
- G is universal gravitation
- M is mass of the Earth
- r is the radius of the circular path
Since the two objects are at the same height from Earth's surface, the distance from the central point (r) will be the same. Thus, the two objects will have equal orbital speed.
