accleration and tension using radius mass of two block & angle

A block of mass m1 = 3.50 kg and a block of mass m2 = 6.00 kg are connected by a massless string over a pulley in the shape of a disk having radius R = 0.25 m, mass M = 10.0 kg. In addition, they are allowed to move on a fixed block-wedge of angle = 30.0° as in Figure P10.61. The coefficient of kinetic friction is 0.360 for both blocks. Draw free-body diagrams of both blocks and of the pulley. (Do this on paper. Your instructor may ask you to turn in these diagrams.) Figure P10.61 (a) Determine the acceleration of the two blocks. m/s2 (b) Determine the tensions in the string on both sides of the pulley. left side N right side N

numerical problems regarding work and energy, linear momentum, and rotational motion

problem1:A neutron in a nuclear reactor makes an elastic head-on collision with a carbon atom initially at rest. (the mass of the carbon atom is 12 times that of the neutron.) what fraction of the neutron's kinetic energy is transferred to tha carbon atom? (express your answer in percent) problem2:A 1400kg rocket sled at rest on level frictionless rails is loaded with 25kg of propellent. It exhaust the propellent in a 15 seconds "burn".The rocket moves at 160m/s after the burn. What average force is experienced by the rocket during the burn? problem3:A rotating flywheel can be used as a method to store energy. If the flywheel has 1.0*10^6joules of kinetic energy when rotating at 400 ra... click for more

Potential and Kinetic energy

A block of mass m = 0.65 kg is fastened to a spring with k = 65 N/m. The block is pulled a distance x = 11 cm from its equilibrium position at x = 0 on a frictionless surface and released from rest at t = 0. v= 1.1 m/s^2 Calculate the potential and kinetic energy of the oscillator when the block is at x = 0.4 A
