Answer:

F = 0.408 N

Step-by-step explanation:

It is given that,

Weight of a wooden block, W = 8 N

Weight, W = mg

m is mass of wooden block

$m=(W)/(g)\\\\m=(8\ N)/(9.8\ m/s^2)\\\\m=0.816\ kg$

Acceleration of the block, a = 0.5 m/s²

Force, F = ma

$F=0.816\ kg* 0.5\ m/s^2\\\\F=0.408\ N$

So, the magnitude of force applied to the wooden block is 0.408 N.
