1. A dragster races down a 400 m strip in 8 s. Its distance, in metres, from the
starting line after t seconds is  
a. Determine the dragster’s velocity and acceleration as it crosses the finish line.
b. How fast was it moving 40m, and 60 m down the strip?

Can someone help with finding the word equations in this scenario? Theres 7.

Last Monday, Ms. Joe was late for school. After quickly getting ready, she rushed out the door, not realizing she left the milk on the counter. Instead, of taking her rusty bike, she figured that driving her car (burning octane) would be faster. Unfortunately, Ms. Joe did not buy the high-grade gasoline, so there were a lot of sulfur contaminants in it. The sulfur contaminants reacted with the oxygen in the air to form sulfur dioxide. And since it was a very humid day, the sulfur dioxide reacted with the water in the atmosphere to form sulfurous acid - component in acid rain. If only she woke up earlier and have taken her bike! She finally arrived on time for the bell. Upon entering the classroom, she knocked over a solution of hydrochloric and, which landed on and reacted with the chalk (calcium carbonate) on her desk. As she went to clean up the spill, some of the acids reacted with the aluminum ring she was wearing.

• The partial pressure of C02 in the lungs can be varied rapidly by the rate depth of breathing. For example, a common remedy to alleviate hiccups increase the concentration of C02 in the lungs. This can be achieved by holding one's breath, by very slow and shallow breathing (hypoventilation), or by breathing in and out of n paper bag. Under such conditions, the partial pressure Of C02 in the air space of the lungs rises above normal. Qualitatively explain the effect Of these procedures on the blood pH-

• A common practice of competitive short-distance runners is to breathe rapidly and deeply (hyperventilate) for about half a minute to remove C02 from their lungs just before running in, say, a 100 m dash. Blood pH may rise to 7.60. Explain why the blood pH increases.

Which image shows both potential and kinetic energy?

Set up a definit integral that yields the area of the region f(x)=sinx

 (fig2)

Your program will take an arithmetic expression as a String input. For Example:

• “1+2*(3/4)”

• “1+2*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14”

• “1+2*[3*3+{4–5(6(7/8/9)+10)}–11+(12*8)/{13+13}]+14”

Program

Your program will determine whether the open brackets (the square brackets, curly braces and the parentheses) are closed in the correct order.

Outputs:

Output 1

1+2*(3/4)

This expression is correct.

Output 2

1+2*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14

This expression is NOT correct.

Error at character # 10. ‘{‘- not closed.

Output 3

1+2*[3*3+{4–5(6(7/8/9)+10)}–11+(12*8)/{13+13}]+14

This expression is correct.

Output 4

1+2]*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14

This expression is NOT correct.

Error at character # 4. ‘]‘- not opened.
