A flywheel has a constant angular deceleration of -2.36 rad/s2.
(a) Find the angle through which the flywheel turns as it comes to rest from an angular speed of 219 rad/s.
(b) Find the time required for the flywheel to come to rest.
What is the least coefficient of friction between tires and road that will allow cars to negotiate the turn without sliding off the road.
a particle's rest mass is 1.25 M0c^2, decays into two identical paricles of mass .45M0 each. calculate the possible velocities of the mother particle
An unstable particle is at rest and suddenly breaks up into two fragments. No external forces act on the particle or its fragments. One of the fragments has a velocity of +0.800c and a mass of 1.87 10-27 kg, while the other has a mass of 4.31 10-27 k..
