Problem: $$

$($of $32)$

Do not round intermediate answers. Give your final answer$($s$)$ to three decimal places. Check your units.

A baseball player releases a ball with the initial conditions shown in the figure. Determine the radius of curvature of the

trajectory:

$($a$)$ just after release, and

$($b$)$ at the apex.

For each case, compute the time rate of change of the speed. $($Hint: This means the tangential component of acceleration.$)$

$($a$)r=$

ft

$($a$)$ v $-$dot $=$

$f\frac{t}{se{c}^2}$

$($b$)r=$

ft

$($b$)$ v$-$dot $=$

$f\frac{t}{se{c}^2}$
