Block B is being pulled forward by a force of 100 N across a flat, frictionless surface. Of the four arrows shown in the diagram above, which, if any, should be removed to make an accurate free-body diagram for block B?

Ablock of mass 1.5 kg slides down an inclined plane that has an angle of 15. if the inclined plane has no friction and the block starts at a height of 3 m, how much kinetic energy does the block have when it reaches the bottom? acceleration due to gravity is g = 9.8 m/s2. a. 6.8 j b. 50.9 j c. 0 j d. 44.1 j
