Traffic merging physics problem

physics help please:)

In the figure, two blocks, of masses 2.00 kg and 3.00 kg, are connected by a light string that passes over a frictionless pulley of moment of inertia 4.231 kg · m2 and radius 17.3 cm. What is the coefficient of friction for the tabletop if the upper block has moved 89.3 cm and is moving at…

In the figure, a block of mass m is moving along the horizontal frictionless surface with a speed of 5.70 m/s. If the slope is 11.0° and the height the block rises is 1.65 m, determine the coefficient of kinetic friction between the block and the incline.

Can any one send me solutions for these questions?

A microscope can locate an electron within a distance of 1A° .Calculate the uncertainty in the measurement of its momentum.

Using uncertainty principle, show that the protons,neutrons and alpha-particles can exist within the nucleus

Give the physical significance of Heisenberg's uncertainty Relation.

Even when shut down after a period of normal use, a large commercial nuclear reactor transfers thermal energy at the rate of 150 MW by the radioactive decay of fission products. This heat transfer causes a rapid increase in temperature if the cooling system fails (1 watt = 1 joule/second or 1 W…
