Answer:
The maximum height of the arrow is 42 (and the units given for the height)
Explanation:
Everything is easier if you make a graph, you can give values to t and replace that values in the function, for example:
When t=0
h(0)=26
If you give some values to t you can see how the trajectory of the arrow is (please look the graphic below)
Now, to find the maximum you have to find the derivative of the function that describes the height of the arrow:
Then you have to take the derivative, and equals to zero to find t:
-32t+32=0
-32t=32
t=1
That is in the time of 1 second the arrow has its maximum height.
Now you have to replace this value in the original function, to find the height of the arrow:
h(1)=-16+32+36
h(1)=42
High pressure systems entail sinking air, while lows entail rising air. High pressure systems form where air converges in the higher levels of the atmosphere. The converging air has nowhere to go and is forced to sink toward the ground. This sinking effect inhibits cloud formation and therefore precipitation.
Answer:
C. Both a and b
Explanation:
Firstly, persons and objects in a moving plane as described in this question, are moving at the same speed as the plane even if there is no individual movement of these objects.
However, this question describes a person sitting still in a moving plane. This means that;
- The person is motionless in relation to everything in the plane i.e the person is not moving even if other things in the plane are.
- The person is in motion compared to everything on the ground i.e. the person is moving at the same speed as the plane, hence, in comparison with the ground, the person is moving.
Therefore, options A and B are correct
Answer: 10.36m/s
How? Just divide 200m by 19.3 and you will get how fast he ran per m/s
