The coefficient of static friction is us= 0.50. Calculate the magnitude of the maximum possible static friction force, in N (i.e. Newtons), which can be generated, if an external force is applied to the block. Use 2 digits of precision in your answer. +X Question 4 Saved A box is at rest on a frictionless slope. The slope is at 25 degrees to the horizontal and the box is tethered to a string which is keeping it from sliding downwards. If the box has a mass of 1,177 grams and g = 9.81 m/sz, determine the magnitude of the tension in the string (in Newtons). Use a single digit of precision for your answer. Question 5 Saved You push your backpack, mass 7.8 kg across the desk with a force of 13.6 i N. Calculate the acceleration of the backpack in m/s2 . Neglect friction forces and give your answer with 2 digits of precision. (You do not need to include a unit vector i in your answer) Question 6 The diagram below shows the Free Body Diagram of the three forces acting on an object of mass 0.16 kg.
