The formula for the height of a rocket fired straight up from the ground with an initial velocity of 128 ft/sec is H=-16t^2+128, where t is the time in seconds. Find the height after 2 seconds. SHOW ALL WORK

OpenStudy (anonymous):

Just substitute 2 for t...The 128ft/sec is just extra unnecessary info.

OpenStudy (anonymous):

so it would be H=-16(2)^2+128?

OpenStudy (anonymous):

yes.
