A 2.0-kilogram block sliding down a ramp from a height of 3.0 meters above the ground
reaches the ground with a kinetic energy of 50. joules. The total work done by friction on the
block as it slides down the ramp is approximately
(1) 6 J
(2) 9 J
(3) 18 J
(4) 44 J

The total work done by friction on the block as it slides down the ramp is 44 J.

The given parameters;

The work done by friction is the change in the mechanical energy of block;

Thus, the total work done by friction on the block as it slides down the ramp is 44 J.

Explanation:

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
