Answer:
B
Explanation:
Friction acts in a direction opposite to the motion of an object
Answer:
Explanation:
Object is Floating in a liquid
weight of object is equal to weight of displaced fluid
i.e.

i.e.
where V and V' is the volume of object and volume of object inside the liquid.
therefore mass of liquid displaced must be equal to mass of object
Initial velocity = 25 m/s, angle 60°
sin (60°) = opposed leg / hypothenuse = Vertical velocity / Initial velocity
=> Vertical velocity = initial velocity * sin (60°) = 25 m / s * 0.866 = 21.65 m/s
