(a) A force F = 10 N is applied in the direction forming an angle = 20°. with the horizontal surface of a material point. Calculate the acceleration of the material point, if its mass is m = 5.0 kg. The force F is progressively increased. How much is F when the material point starts to rise from the ground? And what is its acceleration? (b) Two forces F₁ = 4.0 N ux and F₂ = 5.0 N uy push a body of mass m = 5.5 kg. Calculate the acceleration of mass m.
