4. A car starts from rest and accelerates at a constant rate of 4.0 m/ s2 for 5.0 s. It then accelerates at 5.0 m/s2 to reach a speed of 30
m/s. What distance does the car cover in the second part of its
journey?

What is the answer

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
