A baseball is thrown in a
point in time can
parabolic arc. It's position above the ground at a given
be represented by the quadratic function
p (t)
gt? + vot +
Po, where t ≥ 0, g is -32 ft/sec/sec, Vo is initial velocity,
and po is its initial position above the ground. If the ball was thrown straight up at
20 ft/sec when it was 5 ft above the ground, how high did it go? (Type the number,
do not include units in your answer)
