A diver jumps off a 20 foot high diving board with an initial upward velocity of 4 feet per second. Use the vertical motion model
h=-16t² + vt + s.
PART A:
Using the information above, the vertical motion model of the diver is h-

PART B:
The solutions of the model are t =
and t=

PART C:
Choose the letter that best fits the scenario.
A. There are no real solutions, because the solutions found do not make sense.
B. There is only one solution, because the solutions indicate time and time cannot be negative.
C. There are two solutions, because when solving, there were two solutions that occurred.
D. None of the above because there is not enough information.
Answer: ______

Sagot :

The height is represented by h = -16t² + 4t + 20 and There is only one solution, because the solutions indicate time and time cannot be negative.

How to solve vertical motion models?

We are given the vertical model of the diver's jump as;

h = -16t² + vt + s

where;

h is height

t is time

v is velocity

s is distance

A) We are given;

Distance; s = 20 ft

velocity; v = 4 ft/s

Thus;

h = -16t² + 4t + 20

B) The solution of the model is gotten from;

-16t² + 4t + 20 = 0

Solving this quadratic equation gives;

t = 1.25 seconds or -1 second

C) B. There is only one solution, because the solutions indicate time and time cannot be negative.
