I am trying to do a vertical motion problem and it keeps coming up a ridiculously negative number!
I know the formula is:
. . .h = -16t^2 + vt + s, where
. . ."h" is the height (in feet) at a given time
. . ."s" is the initial height (in feet)
. . ."t" is the time in motion (in seconds)
. . ."v" is the initial velocity (in feet per second)
If the initial height is 8 ft and the initial velocity is 95 feet/sec, how high will the object be in 4 minutes?
I used:
. . .h = -16(240)^2 + 95(240) + 8
. . .h = -16(57,600) + 22,800 + 8
. . .h = -921,600 + 22,800 + 8
. . .h = -898,792
Obviously wrong! What am I doing wrong?
