7. A baseball hit straight up into the air from an initial height of 1 m has a height, h , in metres, after : seconds of h=-4.9' + 40+1, f2 0 a) The ball has a constant vertical acceleration. What is it? b ) When is the velocity of the ball equal to zero? c) What is the position of the ball after a half-second of travel? Product Rule: If f = gok then f' =g'.k+g.k' Quotient Rule: If f = & then f' = g . k- g . k' A 2
