Your answer is partially correct.

A $2\mathrm{.}2-$lb slider is propelled upward at A along the fixed curved bar which lies in a vertical plane. If the slider is observed to have a speed

of $9\mathrm{.}1f\frac{t}{sec}$ as it passes position $B,$ determine $($a$)$ the magnitude $N$ of the force exerted by the fixed rod on the slider and $($b$)$ the rate $v^{}$

at which the speed of the slider is changing $($positive if speeding up$,$ negative if slowing down$).$ Assume that friction is negligible:

Answers:

$N=$

Ib

$v^{}=$

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