Arocket initially at rest on the ground lifts off vertically with a constant acceleration of 2.0 ã 101 meters per second2 . how long will it take the rocket to reach an altitude of 9.0 ã 103 meters?

Time taken, t = 30 seconds

Explanation:

It is given that,

Initial speed of the rocket, u = 0

It is lifted with a constant acceleration of,

Height to be attained,

Let t is the time taken by the rocket to reach an altitude of . Using the second equation of kinematics to find it as :

t = 30 seconds

So, the time taken by the rocket to reach given height is 30 seconds. Hence, this is the required solution.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
