Textbook Question
Chapter 2, Problem 2.17P
A strong softball player smacks the ball at a height of 0.7 m above home plate. The ball leaves the player’s bat at an elevation angle of 35° and travels toward a fence 2 m high and 60 m away in center field. What must the initial speed of the softball be to clear the center field fence? Ignore air resistance.

A boy wishes to throw a ball over a flat roofed school house that stands 12 m wide and 7.5 m high on level ground. Assuming that the ball will leave his hand at a height of 5 m above the ground,determine how far from the wall he should take his hand in order to make the ball clear the roof with least effort, that is, with minimum velocity.
A basketball player shoots toward a basket 6.1 m away and 3.0 m above the floor. If the ball is released 1.8 m above the floor at an angle of 60° above the horizontal, what must the initial speed be if it were to go through the basket?
