Answer:
The object moves 0.0833 m downwards.
The object moves 8.33 cm downwards.
Explanation:
Weight of object = W = 6 × 9.8 = 58.8 N
Mass of liquid displaced = 3.45 kg
Meaning that buoyant force = Fb = 3.45 × 9.8 = 33.81 N
drag force on the object from the liquid is negligible.
Net force acting on the object = ma
Force balance on the object gives
Net force = W - Fb + D
W = 58.8 N
Fb = 33.81 N
D = 0
Net force = 58.8 - 33.81 = 24.99 N
ma = 24.99
6a = 24.99
a = (24.99/6) = 4.165 m/s²
Now, using one of the equations of motion
u = 0 m/s
a = 4.165 m/s²
y = ?
t = 0.200 s
y = ut + ½at²
y = 0 + (0.5 × 4.165 × 0.2²)
y = 0.0833 m
Since the Weight of the body is more than the buoyant force exerted by the liquid on the object, the object moves downwards.
Hope this Helps!!!
