Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

100%

The figure shows a block of mass m resting on a 20° slope. The block has coefficients of friction μs = 0.64 and μk = 0.54 with the surface of the slope. It is connected using a very light string over an ideal pulley to a hanging block of mass 2.0 kg. The string above the slope pulls parallel to the surface. What is the minimum mass m so the system will remain at rest when it is released from rest?

1. Where to go? Diego was travelling 5.00 [km], 60° N of E, then 7.00 [km], 45° S of E, and then 8.00 [km], 30° N of E. At the end of this trek, he realized that in the last leg he should have travelled 5.00 [km], 30° W of N instead of the third path he originally took. A. In component form, what path should Diego take to reach his supposed destination? B. Diego now travelled the path you calculated in A. In component form, what now is his displacement from his initial position? C. Having found treasure, Diego called for an airlift. The airlift is located 50 [km], S, from his initial position. In magnitude-bearing form, determine the path the airlift must take to reach Diego.
