Một vật có khối lượng m = 10,0 kg đang nằm yên trên mặt phẳng ngang thì chịu tác dụng của lực kéo F⃗⃗ theo phương tạo với mặt ngang một góc  = 300 như hình vẽ. Cho biết hệ số ma sát trượt giữa vật và mặt phẳng ngang là  = 0,2. Lấy gia tốc rơi tự do g = 10 m/s2 . Để vật trượt với gia tốc a = 0,50 m/s2 thì độ lớn của lực F phải bằng bao nhiêu?
