Question

PlS help I really need help.very urgentPLS help

Answer 1

Draw a freebody diagram, it will explain it really well

the boat is floating on top of the water, which means that the net acceleration in the y direction must be zero

the boat is not sinking (dominant downwards acceleration/force)
the boat is not flying (dominant upward acceleration/force)

that measn
$F_{net_y} =0$

now, if you drew the FBD, you only have 2 forces acting on the boat.
the upward bouyancy force on the boat and the downward force due to weight

$F_{net_y}= F_{bouyancy} - F_{weight}$

since the net force is equal to zero

$F_{bouyancy} - F_{weight} = 0$

and thus

$F_{bouyancy} = F_{weight}$
