Answer:
D) 11 N
Explanation:
F = mg
In the vertical
30 = m(9.8)
m = 3.06 kg
in the horizontal
F = ma
F(unknown) - 5 = 3.06(2.0)
F(unknown) = 11.12... N
If you float a piece of wood in a container half-full of water that rests on a weighing scale, the weight reading on the scale will increase.
<h3>What is Buoyancy?</h3>
Buoyancy is the force through your fluids or total or submerged bodies. Also known as Archimedes' theorem. The fluid of the direction on the body produces a resultant force but with the direction of the weight, with the opposite direction, upwards.
All material submerged in a liquid under the action of buoyancy, for this reason we have that the value on the scale will be increased with a system of a wood floating in water.

The key is in "they lock together". This tells you this is a complete inelastic collision and therefore you can use the formula:
m1*v1+m2*v2=v(m1+m2)
Plug in numbers:
2000*3+2000*2=v(2000+2000)
so v=2 m/s, obviously in the same direction of motion in which they were both moving.
