A Block has a mass of 50.0 kilograms. the coefficient of static friction between the block and the level floor on which it rests is 0.428 A horizontal force of 618 newtons is applied to the block to the right, as shown. will the block move?

  • physics -

    F(fr) =k•N=k•m•g = 0.428•50•9.8 ≈ 210 N.
    F>F(fr) => the block will move at the acceleration
    a = (F-F(fr))/m = (618 – 210)/50 = 408/50 =8.16 m/s²
