10 Physics questions: Acceleration, speed, air resistance, density, temperature, work
Ignoring air resistance, how fast is the cannonball going when it hits the balloon?
5. A vacationer floats lazily in the ocean with 93% of his body below the surface. The density of ocean water is 1,025 kg/m^3.

Calculations: Volume, Density, Mass, Efficiency, Conversions
Round to the nearest whole number, do not include units.
1g=10^(3) kg, 1cm^3=10^(6) m^3,
Therefore, 4.8 g/cm^3, if converted to kg/m^3, is: 4.8*10^(3)/(10^(6))=4800
8. A lead sphere (D=11.4g/ml) has a mass of 5,361.5 g.

Asteroid Physics Problems
Be sure to fully explain all of your answers. 1) Density
Radius = 1/2 diameter
Density = Mass / Volume = 1000kg / (4/3 x pi x 0.5^3)
Density = 1910.828 kg/m^3
Converting to g/cm^3 for next question:
1910828 g/m^3
1 m^3 = 100cm x 100cm x

Volume of tank = 130 ft^3
= 130 x 0.0283 m^3
= 3.68 m^3
Volume of air displaced = 3.68 m^3
Density of air 1.2 Kg/m^3
