Question

On Mars if you hit a baseball the height of the ball at time t would be modeled by the quadratic function h(t)=-1.85t2+20t+1 how long will the ball be above 17 m

Answer 1

So the motion is parabolic,

Find the two solutions (values for t) to that equation where h(t)=17

Answer 2

thanks but i have to solve it quadratic equation

Answer 3

you could but you'd have to make it equal to 17 first.

\( h(t)=-1.85t^2+20t+1= 17\)

Answer 4

is it like this
0=-1.85t2+20t-12
and also thanks once again

Answer 5

close, its: \(0=-1.85t^2+20t-16\)

Answer 6

no problem !
