An object with a mass of 145 kg has a radius of 13 cm. (I=0.5 mr^2). What is the moment of inertia of the object? If this object has an angular acceleration of 4.25 rad/s^2 what is the torque? A car is traveling east with a mass of 125 kg at a speed of 30 m/s and another car is traveling north with a mass of 750 kg at 45 m/s what is the final velocity after the cars collide?

1. Consider a disc and hoop both of the same mass M, radius R and thickness I. a) Explain why one of these objects has a larger moment of inertia (about an axis through the center of mass and perpendicular to the plane of the object) than the other. What effect does the thickness I have on the rotational inertia? b) Explain how the rotational inertia of the disc may be obtained by adding the...

1. Assuming that the moment of inertia of the support is 0.01345 kg m^2 and to add the disk to the support the moment of total inertia of the support and disk increases to a value of 0.06000 kg m^2, how much is the moment of inertia of the disk? How much is the mass of the disk if it has a radius of 0.15 m and that the moment of inertia is given by I = 0.5 mr? 2....

A special pulley has two hubs where two different strings wrap around either hub. The pulley has total moment of inertia I= 1.6 kg m^2. The smaller hub has radius r1=8cm, and the string wrapped around this hub connects to the mass m1= 200kg. This mass rests on a frictionless plane incline at angle 0=30. The second string wraps around the larger hub with radius r2=25cm and connects to a freely hanging mass m2=25 kg. Determine the angular acceleration of...
