A block of mass m1 = 0.57kg is placed on top of another block of mass m2 =0.97kg, which rests on a frictionless horizontal surface. A horizontal force of 3.37N is applied to the lower block.
What minimum coefficient of static friction between the two blocks will prevent the upper one from slipping?
Illustrate what is the time necessary for crossing if the hunter wishes to move neither upstream nor downstream whilst crossing the river? Draw the vectors to scale on a graph to determine the answer.
While a roofer is working on a roof that slants at 39.0 degrees above the horizontal, he accidentally nudges his 93.0 N toolbox, causing it to start sliding downward, starting from rest.
