FIGURE 8-7 -An Object of Mass M Is at Rest on a Rest

question 55

Short Answer

FIGURE 8-7
-An object of mass m is at rest on a rough inclined plane with height h, length 8 m, and which makes an angle of 30° with the horizontal. The object is allowed to move and it stops on a rough horizontal surface, at a distance of 4 m from the bottom of the inclined plane, as shown in Fig. 8-7. The coefficient of kinetic friction on the inclined plane is 0.4.
(a) What is the speed of the object at the bottom of the inclined plane?
(b) What is the coefficient of kinetic friction for the horizontal surface?

Internal Organs

The critical structures within the body that perform its vital functions, including the heart, lungs, liver, and kidneys.

Pain Receptors

Pain receptors, or nociceptors, are sensory neurons that respond to damaging or potentially damaging stimuli by sending signals to the brain, which interprets them as pain.

Spinal Cord

The long, thin, tubular structure made up of nervous tissue, which extends from the brainstem down the back, and is responsible for transmitting neural signals between the brain and the rest of the body.
