A 3.5-kg block rest on a horizontal tabletop. A cord is attached to this block, the cord passing over a pulley at the edge of the table. at the end of the cord is hung another block weighing 5 N. Determine the tension in the cord and the distance the blocks moved after 2 seconds.

A 19.3 lb object has the acceleration components ax 4x = (0.35) + (0.73) ₁ ay = (10.3) - (0.79) What is the magnitude of the net force Fnet acting on the object at time t = 3.27 s? Fnet = What is the direction of the net force at this same time? Give the answer as a number of degrees 0 counterclockwise from the +x-axis. 0= N

When two horizontal forces are exerted on the car, 250 N forward and 220 N backward, the car undergoes acceleration. What additional force is needed to produce non-accelerated motion.

A box with a mass of 5 kg sits on a flat table. The Earth pulls on this object with force equal to the weight of the object (49N).    If this is the action force, what is the reaction force?   The table pushing down on the floor with force of 49N.      The box pushing down on the table with force of 49N.      The normal force pushing up on the box with force of 49N.      The box pulling upward on the Earth with force 49N.
