The mass (m) equals 1.02 kg is sliding on a rough horizontal surface as shown. A force F = 8.41 N is applied at an angle of 38.7 degrees. Calculate the acceleration (a) (in m/s2) of the mass on the surface if the coefficient of kinetic friction is 0.112. Use g = 9.8 m/s2 and express your result to three significant digits.
