A block is free to slide without friction on a horizontal table. William exerts a constant force of 5 N on the block. The direction of the force is 37◦ with respect to the horizontal. William keeps applying the force on the block as it moves a distance of 10 meters on the table top. A

  1. a) How much work was done by the William’s force?

  2. b) How much work was done by the force of gravity?

  3. c) Howmuchworkwasdonebytheforcethatthetableexertsonthe

In the figure, a block weighing 16.4 N, which can slide without friction on an incline at angle ? = 30.0°, is connected to the top of the incline by a massless spring of unstretched length 0.430 m and spring constant 100 N/m. The block is initially at its equilibrium position. (a) How far from the top of the incline is the block’s equilibrium point? (b) If the block is pulled slightly down the incline and released, what is the...
