Figure shows an initially stationary block of mass m on a floor. A force of magnitude 0.500mg (where m is the mass and g is the gravitational acceleration) is then applied at upward angle 0 = 20°. What is the magnitude of the acceleration of the block across the floor if the friction coefficients are i µ = 0.600 and u = 0.500 ii ls = 0.400 and uk = 0.300? Answer: i) a=0 since no motion ii) 2.17 m/s? Figure shows an initially stationary block of mass m on a floor.
