Explanation:
Let the velocity of puma be a.
Consider the vertical motion of puma
We have equation of motion v² = u² + 2as
Initial velocity, u = asin45
Acceleration, a = -9.81 m/s²
Final velocity, v = 0 m/s
Displacement, s = 3.7 m
Substituting
v² = u² + 2as
0² = (asin45)² + 2 x -9.81 x 3.7
a² = 145.19
a = 12.05 m/s
Speed required is 12.05 m/s
<u>Answer: </u> <em>Q= Air resistance</em>
<u>Description: </u>
The box release two forces acts on it, when it is falling from the building.
<em>1. Its weight, 2. Air resistance</em>
- As this point its weight is much greater due to the force of gravity on the objects, so it accelerates downwards.
- As its speed increases so does the drag on the object so its acceleration starts slow down until it reaches to zero. At which point air resistance will be equal to weight of the object leaving a resultant force of zero.
Answer:
It would because the shape of the rocket is designed to be able to slice through the air as smooth as possible and now you may be thinking that air is already smooth but when you try to push something as large and heavy like a rocket then the shape of the rocket will be very important. The bottom of the rocket is flatter then the top so it is not designed to fly smoothly through the air. So the rocket would fall vertically downward(If it was still in one piece)because of it's shape. It is easier for the top of the rocket to go smoothly through the air then the bottom.
