One disadvantage of this type of power is that it still pollutes the air

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

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
