Question

after a golfer hits a golfball, the leaves the ground with an initial vertical velocity of 100 feet per second.

how to graph this?
how to find the seconds to reach the maximum height
how to find when the maximum height is reached?
how to time the object that is in the air (or person)? Help.!

Answer 1

please help!

Answer 2

The x axis is the number of seconds.
The y axis is how many feet traveled per second.

Answer 3

Now, every second you go to the right, on the x axis, you would go up 100, on the y axis.

Answer 4

2) It depends on how hard he it the ball.

Answer 5

are we supposed to assume the ball goes straight up in the air?

Answer 6

seems very unlikely
you need to know the angle at which the ball is hit
but if the question really means it goes straight up (guy needs lessons) then you can model it as
\[g(t)=100t-16t^2\]

Answer 7

max height is second coordinate of the vertex, time in the air is solved via
\[100t-16t^2=0\]
