Question

If an object is projected upward with an initial velocity of 124ft per second, its height 'h' after 't' seconds is h=-16t^2 +124t find the height of the object after 2 seconds.

Answer 1

You have a formula for the height at any desired time:
\[h(t) = -16t^2 + 124t\]All you need to do to find the height after 2 seconds is plug in \(t = 2 \text{ seconds}\) and turn the crank...

Answer 2

so its h(2)=-16(2)^2+124(2) right??

Answer 3

yes, and that equals?

Answer 4

my answer was 184

Answer 5

Yes, 184 ft is correct as the attached diagram shows.
