$84.0ft$ , rounded to one decimal place

Explanation:

Applicable Kinematic equation is
$v^2-u^2=2as$
where $v, u, a and s$ are final velocity, initial velocity, deceleration and distance covered respectively.

Now, $50mphxx(1760xx3)/3600=73.3333fps$
Inserting given and calculated values

$0^2-73.3333^2=2(-32)s$
$=>s=73.3333^2/64$
$s=84.0ft$ , rounded to one decimal place
