Which statement is true? A.
Inertia causes bodies to slow in their motion, unless they’re pushed by a force.
B.
Inertia resists changes to the state of motion of a body.
C.
Inertia decelerates a body.
D.
Inertia is due to friction.

Explanation:

B  

Think of inertia of getting into a car accident without a seat belt although the car stops you will not you would likely fly out the window

c

Got 100 on edg21

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
