Answer: 38 feet.

Step-by-step explanation:

The equation of motion of a body thrown vertically upwards:

$\displaystyle\\\boxed {h=h_0+v_0t-\frac{gt^2}{2} \ \ \ \ \ (1)}$ ,

$h_0=2 \ feet\ \ \ \ v_0=50\ feet\ per\ second.$

Substitute in formula (1) the value t=2 c:

$h=2+50*2-16*2^2\\h=2+100-16*2*2\\h=102-64\\h=38\ feet.$
