For increased weight in the same volume add old nuts, bolts, washers, etc., the bigger the better, that litter everybody39s shop and stir them into the concrete mix or place them in the ball form as you fill it with the concrete. Steel is about 3 times denser than concrete so the weight will add up quickly.

See Details >A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix. Determine the Density of Concrete. Density is the measure of mass for a given volume and is defined by the
See Details >To calculate the momentum of the ball right before it hits the floor, you need the velocity right before hitting the floor. The ball is in free fall for 1m so to calculate the velocity, you can use free fall kinematics or conservation of energy of the ballEarth system i b.
See Details >To check for the hollow sound, you can use a golf ball and drop it onto each tile to ensure proper installation. The hollow sound indicates that the tiles have debonded or were never bonded properly in the first place. If the tile is installed over concrete and is well bonded, when the golf ball is dropped onto it, it will make a lowerpitched
