An unstable atomic nucleus of mass 1.60 x 10-26kg initially at rest disintegrates into three particles. One of the particles, of mass 5.18 x 10-27kg, moves in the y direction with a speed of 6.00 x 106m/s. Another particle, of mass 8.44 x 10-27kg, moves in the x direction with a speed of 4.00 x 106m/s.
Find the Velocit of partical 3, and find the total kinetic energy increase in the process.
The rope shown in the figure attached hereto is wound around a cylinder of of mass 4.0 kg, radius 10 cm and I =0.020kgm2, where I is the moment of inertia about an axis along the cylinder axis. If the cylinder rolls without slipping, what the line..
