Use the vertical motion model
h= -16t2+vt+s
the 2 stands for squared.
You and a friend are playing basketball. You can jump with an initial velocity of 12 feet per second. You need to jump 2.2 feet to dunk a basketball. Your friend can jump with an initial velocity of 14 feet per second. Your friend needs to jump 3.4 feet to dunk a basketball.
Can you dunk the ball? Can your friend? Justify your answers.
show your work, please.
one more question..
suppose you can jump with an initial velocity of 11.5 feet per second and your friend can jump with an initial velocity of 15.5 feet per second. How, if at all, would this change your answers to the last question?

Can't answer this without knowing what s is.
For each of these, you'll plug in v and h, subtract h from both sides, then use the quadratic equation to see what times fit the equation.
If you get an imaginary answer, then you will not be able to dunk. If you get a real answer, then you can dunk.
