The buoyancy force is only dependent on the amount of water displaced. If each of the blocks are a cubic meter, and each of them is submerged, each will displace a cubic meter of water, so the buoyancy force will be the same.

It will be the same for ANY material that is a cubic meter in volume. The NET forces will be different, since the force of gravity will act on different masses of material in the cube, but the buoyancy force will not be different. If the wood is permitted to float, it will not be fully submerged, and so will not displace a full cubic meter, and so the buoyancy force will be less.

So the completed VF will continuously be greater desirable than V1 as V1 is integrated in it. Related Questions Conceptual Physics homework help? Conceptual Physics homework help pleaseeee!?

Try to balance two magnets stuck together instead of one against a four magnet tower. Take a magnet tower of three magnets and rest it on its side. Trace the front edge of the magnet tower and try to balance a single magnet a little more than an inch away from it. Using your ruler, draw a line and measure the distance from the very edge of the magnet tower to this mark. Starting with the sideways five magnet tower and a single balancing magnet, hold the magnet tower steady on the front edge line.

Carefully remove one magnet from the back of the magnet tower and observe the balancing magnet. Remove one magnet at a time from the back of the magnet tower and observe. Answer in complete sentences! Was it possible to balance a single magnet against a four magnet tower? Why or why not? What did you notice about the height of the single balancing magnet as magnets were removed from the back of the magnet tower?

What else did you investigate about these magnets interactions? PE Stair Ditto front - E 4. Intro to Energy Ditto all G 6. Energy Practice Ditto front - Y 7.

Once you find the average time from your 9 trials you can use it to solve for the velocity.

Since the marble traveled along that last 50 cm 0. All of the Potential Energy at the top has become Kinetic Energy at the bottom.

If she had that much kinetic energy at the end of her dive, she had that much potential energy at the beginning of her dive. Momentum Study Guide purple "P" 4. Momentum Practice Problems , 8, 10 pink "S" 7. Momentum Practice Problems , 9, red "E".

The mass is the mass of the truck kg PLUS the mass of the load kg. Use the momentum you found in 5 and the mass of just the truck. It should be going faster since it lost mass. This is one of the collision problems we talked about in class. Look at the picture below. The momentum after is equal to the momentum before. So if you take the total momentum before, and divide by the total mass you will get the velocity. This is similar to the gun recoil problem we did in the lecture today. Initially, since they are both at rest, they have zero momentum.

Afterwards, they have to have zero total momentum. Therefore, the boy and girl have to have equal but opposite momentum. Solve for the velocity.

First you have to find the velocity of the runner. Then you can find the momentum. For the Study Guide and 2, 7, 9, refer to your reading notes and what you learned in class today.

And the Net Force Practice Ditto from yesterday!

You are given the mass, and you know the acceleration due to gravity. You want to know the weight aka F g. Multiple the mass by the acceleration due to gravity.

The conversion to pounds is 4. You are given the force of gravity, and you know the acceleration due to gravity. You want to know the mass. Divide the Force of gravity by the acceleration due to gravity. Projectiles Ditto I 4. Sports Projectiles Ditto HT 6. CD front only no stamp back is Extra Credit. This is just like your warm-up question! Because there is no acceleration in the x horizontal direction, there is nothing that would speed up or slow down Harry. This one is a little trickier.

Sice you know how high 20 m the ball started, you can figure out how long it took to fall. Because remember, an object dropped or shot will fall vertically the same way! So you can use: Solve for the time it takes the object to fall. Now that you know how long the ball is in the air, you can figure out how fast is travels that 60 m.

Sep 30,  · Best Answer: 1) You should have been taught about the equations relating speed acceleration, time and distance. One is simply speed = acceleration * time, v =a*t. Another is one that says distance covered is average velocity * time. since the sled starts at rest, and acceleration is constant, the average speed is half the final counting.ga: Resolved.
