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!!!
Answer:
Explanation:
As we know that velocity as a function of position is given as
now in order to find the acceleration we can use that rate of change in velocity is known as acceleration
So we will have
Now by Newton's 2nd law we have
Answer:
Δv = vf - vi = 45 - 20 = 25 m/s
