a large box of mass 11.4 kg sits on a ramp that makes an angle of 30.1 degrees with the horizontal. The surface of the ramp is rough and the oefficients of static and kinetic friction are given as 0.56 and 0,38, respectively. We exert a force up the ramp (parallel to the ramp surface) so hat the box does not move. Calculate the maximum and the minimum magnitude of the force we can exert so that the box does not move. Enter the difference between the maximum and the minimum force values here: Fmax-Fmin (in Newtons). On your paper, show all the forces on free-body diagrams, clearly show your work, your derivation and calculations. Make sure to include your physics-based reasoning.

A person , sunbathing on a warm day, is lying horizontally onthe deck of a boat. Her mass is 59 kg, and the coefficient of staticfriction between the deck and her is 0.70. Assume that the person ismoving horizontally, and that the static frictional force is the onlyforce acting on her in this direction . (a) What is the magnitude of the static frictional force when the boat moves with a constant velocity of +8.0 m/s? (b) The boat speeds up with an acceleration of 1.6 m/s2 and she does not slip with respect to the deck . What is the magnitude of the static frictional force that acts on her? (c) What is the magnitude of the maximum acceleration the boat can have before she begins to slip relative to the deck ?

A 6 kg crate is pulled by a force of 185 N at an angle of 18^0 from the horizontal. A constant frictional force of 47 N resisted the crate. Calculate the net force experiences by the crate

: A block of 100 N is placed on an inclined plane having an inclination of 25 degrees with horizontal. A force of 75 N is required to move it up along the direction of the plane.   Find the coefficient of friction between the block and t he plane

A Smart Fortwo® car has a mass of 730 kg, which we assume on a flat surface is evenly distributed over its four tires. What is the maximum value of static friction on one tire if the coefficient of static friction between the tire and the road is 0.85? Note: In Iceland, though Smart cars are popular, there are special warnings about where to park them because the local winds can be strong enough to move the cars if they are not sheltered.
