1.calculate the end velocity of a rocket that traveled 16km in 2 seconds.
distance
time
2.calculate the rockets acceleration m with a start velocity of 0m/s and the end velocity from #1 for 10 seconds.
(final velocity- start velocity)
time
* be sure to include units!

Explanation:

1. Distance covered by the rocket,

Time taken, t = 2 s

The velocity of rocket is given by:

v = 8000 m/s

So, the velocity of a rocket is 8000 m/s.

2. Starting velocity of the rocket, u = 0

Final velocity, v = 8000 m/s

Time taken, t = 10 s

Change in speed, (v-u) = 8000 m/s

Acceleration of rocket is given by :

So, the acceleration of the rocket is . Hence, this is the required solution.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
