A 15 kg mass attached to a cord that is wrapped around a pulley and released from rest. the pulley has mass of 5 kg but is frictionless. consider the cord as mass less, inelastic and frictionless.
a) determine tension in the cord?
b) torque in the pulley?
c) determine the acceleration of the falling mass?
d)determine the time it would take the mass to fall 5 meters.
e) determine angular momentum of the pulley 10 sec following the released of the falling mass from rest.
f) detrmine the total kinetic energy of the system 10 seconds following the release of the falling mass from rest.
