Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points The horizontal surface on which the objects slide is frictionless. The acceleration of gravity is 9 . 8 m / s 2 . 3 kg 8 kg 5 kg F F r If F = 23 N and F r = 3 N, what is the magnitude of the force exerted on the block with mass 8 kg by the block with mass 5 kg? Answer in units of N. 002 (part 1 of 3) 4.0 points Two forces, 446 N at 8 and 401 N at 35 are applied to a car in an effort to accelerate it. 3718 kg 446 N 8 4 1 N 35 What is the magnitude of the resultant of these two forces? Answer in units of N. 003 (part 2 of 3) 3.0 points Find the direction of the resultant force (in re lation to forward, with counterclockwise con sidered positive). Answer in degrees from the positive xaxis, with counterclockwise positive, within the limits of 180 to 180 . Answer in units of . 004 (part 3 of 3) 3.0 points If the car has a mass of 3718 kg, what magni tude of acceleration does it have?...
