3.A ball is thrown into the air with an initial velocity of 15 m/s. a.How long does it take the ball to reach maximum height?b.W
ehidna [41]

Answer:  a) = 1.5 sec.  b= 11.5 m. c=0  d= 1.5 sec.

Explanation:

a) Once thrown into the air , the only influence on the ball is gravity, so, we can conclude that the acceleration acting on the ball is the one due to gravity, i.e., g= 9.8 m/sec².

Applying the definition of acceleration, we can write the following equation:

a= (vf-vo) / t   ⇒ g = vf-vo / t. (1)

Now, when the ball reaches to his maximum height, it stops momentarily, and then starts to fall, so for this height, we can write vf=0.

Replacing  in (1), and solving for t, we get:

t = (0 -vo) / g = -15 m/s/ - 9.8 m/sec² (Taking upward as positive  direction)

a) t= 1.5 sec.

Replacing this value in the kinematic equation for displacement, when vo=15 m/s, we get:

hmax: 15 m/sec . 1.5 sec -1/2. 9.8 m/sec². (1.5 sec) ² (2)

b) hmax= 11.5 m

c) vf= 0 (as explained above)

Finally, in order to know how long the ball takes to return to its initial height, we know that for the falling part of the trajectory, vo=0, so we can write the equation for displacement as follows:

h=-hmax (because it returns to the same starting point)= 1/2 gt²=-11.5 m

Solving for t, we get:

d) t=1.5 sec.

It can be seen that the time used in going up, it is the same for going down, to travel the same distance.

This result is completely general and applies to any free fall problem.

To instruct Oracle11 g to sort data in ascending order, enter ____ after the column name in the ORDER BY clause.
Paha777 [63]

Answer:

A. ASC

Explanation:

In Oracle11 g ORDER BY clause is used to sort data andit is also used in mysql ,ms access.Though we not to mention ASC to sort in increasing order because by default it sorts the data in ascending order if we do not mention ASC or DESC.To sort in descending order we have to mention DESC.

So the correct answer to this question is ASC.

Write a program to draw a text-based graph of a mathematical function f(x)
Makovka662 [10]
I have a very good example of the program you need written on Python. You can use this (sorry for bad tabulation):
import math import math def main(): function = input("Enter a function f(x):\n") x = 0 y = 0 for rows in range(10,-11,-1): for col in range(-10,11,1): x=col roundfx = round(eval(function)) if roundfx == rows: print("o", end="") if rows==0 and col==0 and not rows == roundfx: print("+", end="") if col == 0 and not rows == 0 and not rows == roundfx: print("|", end="") if rows==0 and not col==0 and not rows == roundfx: print("-", end="") else: if not rows == 0: if not col == 0: if not rows == roundfx: print(" ", end="") print() main()
