The system shown below is released from rest. The m_b = 26 kg block is 2 m above the ledge. The pulley is a uniform disk with a radius of 10 cm and mass m = 6.0 kg. Assume that the string does not slip on the pulley. (a) Find the speed of the 26 kg block just before it hits the ledge. (b) Find the angular speed of the pulley at that time. (c) Find the tensions in the...

Problem 3: Determine the acceleration of block B, acceleration of block A, and the tension in the cable if the system is released from rest. The coefficient of static and kinetic friction between block A and the wedge surface are js = 0.2 and uk = 0.15, respectively. Neglect masses of the pulleys and associated friction in the pulleys. Consider ma = 15 kg and mp = 8 kg. FBDs and kinetic diagrams for blocks A and B is mandatory....

Consider the following three cases 1. The finger is pushing but not hard enough. Neither block moves 2. The finger is pushing hard enough that the two blocks are speeding up 3. The blodies have sped up, and are now moving at a constant speed. The finger still has to push to keep them going at a constant velodty. In all cases where the blocks are moving, they are moving together. (Block is not sliding on block A.) Block A...

1) A block of mass m = 0.52 kg is attached to a spring with
force constant 119 N/m is free to move on a frictionless,
horizontal surface as in the figure below. The block is released
from rest after the spring is stretched a distance A = 0.13 m.
(Indicate the direction with the sign of your answer. Assume that
the positive direction is to the right.)

a)How long does it take an electron to move 50 cm, from rest, in a uinform E-field of 500 N/C? (The mass of an electron is 9.11X 10^-31 kg) b) An electron, initially at the origin, is projected into a uniform E-field (E=10000 N/C) that is oriented along the +y axis. If the initial velocity of the electron was 160 m/s along the +y axis, how long will it take for the electron to reach its maximum y position?
