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
The required answer is 1.16 u.
<h3>
Solution:</h3>
= m1v1 - m2 v2/v2 - v1
v1 = 4.7 * 10^6
v2 = 3.3 * 10^7
m1 = 14 u
m2= 1 u
On substituting in the formula,
= (14 * 4.7 * 10^6 - 1 * 3.3 * 10^7)/3.3 * 10^7 - 4.7 * 10^6
= 1.16 u

Answer:
The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather.
Explanation:
Generation of wind
Answer:
40 N
Explanation:
We are given that
Speed of system is constant
Therefore, acceleration=a=0
Tension applied on block B=T=50 N
Friction force=f=10 N
We have to find the friction force acting on block A.
Let T' be the tension in string connecting block A and block B and friction force on block A be f'.
For Block B
Where 
=Mass of block B
Substitute the values
For block A
Where 
Mass of block A
Substitute the values
Hence, the friction force acting on block A=40 N
