A17.5 kg block is dragged over a rough, horizontal surface by a constant force of 167 n acting at an angle of 30◦ above the horizontal. the block is displaced 23.9 m, and the coefficient of kinetic friction is 0.136. the acceleration of gravity is 9.8 m/s 2 . 17.5 kg µ = 0.136 167 n 30 ◦ if the block was originally at rest, determine its final speed. answer in units of m/s.

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.
