Problem

A ball is thrown vertically upward from the top of a

15\,\text{m}

high building with a speed of

25\,\text{m/s}

. Neglecting air resistance, what is the speed of the ball just before it strikes the ground at the base of the building? (Take

g = 9.8\,\text{m/s}^2

.) (a)

25\,\text{m/s}

(b)

30.3\,\text{m/s}

(c)

18.2\,\text{m/s}

(d)

40.0\,\text{m/s}
