A 1000 kg rocket carrying 25 kg of fuel and oxygen rises at a velocity of 305 m/s. If all the mass of fuel and oxygen is burned
Thepotemich [5.8K]

If all the mass of fuel and oxygen is burned to form gases of combustion, the downward velocity of these gases would be 12,505 m/s.

<h3>Conservation of linear momentum</h3>

The principle of conservation of linear momentum states that, the total momentum of an isolated system is constant.

The downward velocity of thes gases is calculated as follows;

v1(m1 + m2) = v2(m2)

305(1000 + 25) = v2(25)

312,625 = 25v2

v2 = 312,625/25

v2 = 12,505 m/s

Thus, If all the mass of fuel and oxygen is burned to form gases of combustion, the downward velocity of these gases would be 12,505 m/s.

In order for a space shuttle to leave Earth, it must produce a great amount of thrust. Its rocket boosters create this thrusting
bonufazy [111]

Answer:

Orbit

Explanation:

The term that describes motion of the shuttle around earth is called as<em> Orbit.</em>

The orbit is defined as a regular repeating path that object takes around another.

The shuttle circles around the earth at a constant distance from earth surface is because of earth gravity and forward motion of earth.

18. A person pulls horizontally with a force of 64 N on a 14-kg box. There is a force of friction between the box and the floor
MA_775_DIABLO [31]
  • since force=massxacceleration
  • therefore acceleration=force/mass
  • the resultant force=the acting force on the object-the frictional force
  • the resultant force=64-36=28N
  • therefore the acceleration=28/14=2m/sec^2
