Question 3 (1 point) A block of mass (6.9x1040) kg is stationary on a horizontal surface. The coefficient of static friction u= (6.940x10*0). Calculate the magnitude of the maximum possible static friction force which can be generated, if an external force is applied to the block. Use 2 s.f. in your answer. FN +X F 4 W = mg Note: Your answer is assumed to be reduced to the highest power possible. Your Answer. 10 Answer Question 4 (1 point) An object of mass (9.40x10^1) kg is sliding along a surface where the coefficient of kinetic friction is (3.8x10^-1). Calculate the magnitude of the acceleration to 2 5f (you are asked for the magnitude. so it must be a positive number). Note: Your answer is assumed to be reduced to the highest power possible Your
