Please help this question!!

A force of 10N is applied downward at an angle of 30 degree with respect to the horizontal on a block. There is friction between the block and the floor and the block remains Stationary. What is the magnitude of the normal force acting on the block? FN = 10.5 N FN= 12.1 N FN =16.8 N FN = 20.2 N FN = 24.6 N The coefficient of friction between the floor and block is mu = 0.8. What is the magnitude of the frictional force acting on the block? Fmu = 5.2 N Fmu = 8.7 N Fmu = 10.6 N F mu = 12.0 N Fmu = 13.4 N If you are driving in your car and make a sharp turn to the right, your body tends to lean to the left, why? Initially there is a force on your body to the left until the car seat pulls you back to the right. Initially your body tries to stay in a straight line but your lower body begins to move to the right. The leaning comes from your equilibrium system and has nothing to do with forces acting on your body. At an amusement park, some physics students are on a ride where they stand against the wall in a cylindrical apparatus that begins to rotate around its center. Once they are moving fast enough the floor drops and they "stick" to the wall due to friction. The radius of the cylinder is R = 3.5 m and the minimum speed the ride must move the people at to keep them from sliding down the wall is 10 m/s. What is the coefficient of static friction between the student and wall?
