Sorry These Are Out Of Order
"6" if you increase either mass or velocity the momentum of an object increases proportionally if you double the mass or velocity you double the momentum
"5" that it will turn to its original shape after it is let free of the force hope this helps
"4" Archimede's principle states that a body immersed in a fluid is buoyed up by a force (buoyant force) equal to the weight of the fluid displaced by the body.
So If I place a 5 oz rock into a glass of water, and 5 oz of water is displaced, the rock therefore weighs 5 oz
"3" To find if the stone will sink, we have to find out the density of the stone.
Density = mass/volume = 100g/10ml = 10g/ml
To stone will sink because it has a higher density.
"2" a free-body diagram shows the vectors for all the force acting on the body the resultant vector found by summing all the individual vectors represents the net force.
"8"
The formula for computing the final speed of a perfectly inelastic collision is
m1V1 + m2V2 = (m1 + m2)Vf
in this case the mass are equal so
m1V1 + m1V2 = (m1 + m1)Vf
m1(V1+V2) = 2(m1)Vf
thus
(m1(1000 + 0)) / 2m1 = Vf
Vf = 500 m/s
Hope my answer would be a great help for you.
