Question 2 5 pts Iflual 36.73 ft , determine the height of the ball (h) in feet when x = 25 ft. s C 30° B h А 10 ft 7 ft -25 ft -5 ft-

Answer 1

Along x-direction (no acceleration);

$\Rightarrow 25 = 0 + (36.73cos30^o)t$

$\Rightarrow t = 0.786\;\;s$

Along y-direction (downward gravity);

$s_y = (s_y)_o + (v_A)_yt - \frac{1}{2}gt^2$

$\Rightarrow h = 7 + (36.73sin30^o)(0.786) - \frac{1}{2}(32.2)(0.786)^2$

$\Rightarrow h = 11.489\;\;ft$

$\Rightarrow h = \mathbf{11.5}$
