16)A 30.0-kg block is being pulled up a 25.0° slope by a force of 575 N which is parallel to the slope, but the block does not slide up the slope. What is the minimum value of the

2. An incline of the dimensions shown rests on the ground. Two boxes of equal mass are attached by a rope of negligible mass strung around a pulley at the top of the incline. The coefficient of static friction for 5 m the box on the incline is 0.6 and the coefficient of kinetic friction for the box on the incline is 0.5 10 m A) If it starts from rest at the top of the incline, how long does it take the box hanging in the air to reach the ground? B) What velocity does it have halfway to the bottom?

1. Two blocks are positioned on surfaces, each inclined at the same angle of 42.8 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 2.07 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.510. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2? 2. Two blocks are positioned on surfaces, each inclined at the same angle of 49.5 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 2.24 kg, and this time there is NO friction. What is must be the mass of the white block if both blocks are to slide to the LEFT at…

2) A 95kg box rests on a surface where the coefficient of static friction is 0.59. Determine the minimum force to apply on the box to have it start moving.
