Answer:
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
