1. A batter hits a baseball that, when the ball is coming back down from its highest point, descends further and then manages to just clear a 3.25 meter fence on an otherwise level playing field. The batter makes this hit by hitting the baseball from a height of 90.0 cm off the ground with an initial velocity of 38.0 m/s [E45.0U] (or, east and up by 45.0 above the horizontal). (a) How far away is the fence? (horizontal distance only) (b) How long does it take for the ball to just pass the fence? (c) How far past the fence does the baseball go before it hits the ground? (horizontal distance only) (d) How long is the ball in the air from when it leaves the bat until it hits the ground? (e) What is the velocity of the ball as it just passes over the fence? (give full vector answer) (f) What is the impact velocity of the ball (i.e. an instant before it hits the ground)? (give full vector answer) (g) What is the maximum altitude of the ball?
