A solid cylindrical object has a mass-density of rho = 3000kg/m^3 a radius of 0.05 meters, and a height of0.2m. What is the total mass of this cylinder? What is its mass-moment of inertia of this cylinder about an axis (a) passing through its center of mass? What is the moment of inertia of this object about an axis (b) parallel to the axis (a), but 2cm offset from it as shown? Momentum & Impulse: A spaceship with a mass of 100,000kg is in space (ignore gravitational effects). It has a rocket that provides a thrust force given by F = 500,000N middot e^-0.2 t with t in seconds. The spaceship is travelling at 75m/s, and it uses the rocket for 9 seconds. What is the impulse provided by the rocket? What is the final velocity of the spaceship?
