Answer:
Approximately , assuming that the rocket had no propulsion onboard, and that air resistance on the rocket is negligible.
Explanation:
Initial velocity of this rocket: .
When the rocket is at its maximum height, the velocity of the rocket would be equal to . That is:
.
The acceleration of the rocket (because of gravity) is constantly downwards, with a value of .
Let denote the distance that the rocket travelled from the launch site to the place where it attained maximum height. The following equation would relate
to
,
, and
:
.
Apply this equation to find the value of :
.
In other words, the maximum height that this rocket attained would be .
Again, assume that the air resistance on this rocket is negligible. The rocket would return to the ground along the same path, and would cover a total distance of .
<h2>The acceleration of car is 0.2 ms⁻²</h2>
Explanation:
When the car moves , the distance covered is calculated by the relation
S = u t + a t²
In this question u = 0 , because car was at rest initially
Thus S = a t²
here S is displacement and a is the acceleration of car
Therefore 360 = a ( 60 )²
Because time taken is one minute or 60 seconds
Therefore a =
or a = 0.2 m s⁻²
