An iron ball is bobbing up and down on the end of a spring. the maximum height of the ball is 46 inches and its minimum height is 18 inches. it takes the ball 2 seconds to go from its maximum height to its minimum height. which model best represents the height, h, of the ball after t seconds?

The equation for height is

Step-by-step explanation:

we are given

An iron ball is bobbing up and down on the end of a spring

So, height function must be trigonometric in nature

So, we can use formula

now, we can find A , B and D

Calculation of A:

maximum height 46 inch

minimum height =18 inch

so,

Calculation of B:

It takes the ball 2 seconds to go from its maximum height to its minimum height

So, half of time period is 2 sec

now, we can use period formula

we can find B

Calculation of D:

Max=46

min=18

now, we can plug these values into formula

and we get
