A rotating wheel requires 4.7 s to rotate
through 33.5 rev. Its angular speed at the
end of the 4.7 s interval is 45.5 rad/s.
What is its constant angular acceleration?
Assume the angular acceleration has the same
sign as the angular velocity.
Answer in units of rad/s2...
There is a cross shaped object with masses on each arm, the arms are different lengths and they are perpendicular to each other. the longer rod, (7m radius from center) has two 12kg masses, one on each end. The shorter rod (3.5m radius from center) has two 24kg masses one on each end...
1. Find the horizontal displacement of a 24kg mass on a tabletop as a 5.4kg mass drops 8.4cms. they are connected by a string, run through a pulley. The string and pulley are mass less and frictionless. Then find the acceleration of the 24kg mass. Then find the tension of the string between...
