Acart is given an initial velocity of 2 m/s and experiences a constant acceleration of 2 m/s2. what is the magnitude of the cart's displacement during the first 6 s of its motion?

48 m

Explanation:

Since we are dealing with constant acceleration, we can use the following equations:

(1)

(2)

Where:

is the cart’s final velocity

is the cart’s initial velocity

is the cart's acceleration

is the time

is the cart's displacement

So, firstly we have to find from (1):

(3)

(4)

Isolating from (2) and substituting (4):

(5)

(6)

Finally:

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
