Two forces are applied to a car in an effort to accelerate it. The first force, F1 = 328 N, is applied at an angle α = 35° to the forward dashed line. The second force, F2 = 544 N, is applied at an angle β = 8° to the forward dashed line. (a) What is the resultant of these two forces? (b) If the car has a mass of 3150 kg, what acceleration does it have?
