Centripetal acceleration depends directly on the square of the object's speed and inversely on the radius of the circle.

A-True

B-False

True.

Explanation:

The formula for the centripetal acceleration of an object can be calculated by the formula as follows :

Where

v is the speed of an object

r is the radius of the circle

It means, the centripetal acceleration depends directly on the square of the object's speed and inversely on  the radius of the circle. Hence, the given statement is true.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
