Question

$c a r space w h e n space p a s s e s space t h r o u g h space a space c o n v e x space b r i d g e space e x e r t s space a space f o r c e space o n space i t space w h i c h space i s space e q u a l space t o$

$N o n e o f t h e s e$
$= \sqrt{(2)^{2} + {(\frac{900}{500})}^{2}} = 2.7 m \vec{e} s^{2}$
$= \sqrt{a_{t}^{2} + a_{c}^{2}}$
$9.8 m / \sec^{2}$

The correct answer is: $N o n e o f t h e s e$
