mata (jpm2873) – HW #4 – Antoniewicz – (57420) 1 This print-out should have 14 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0points 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(part1of3)4.0points 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 8 401 N 35 What is the magnitude of the resultant of these two forces? Answer in units of N. 003(part2of3)3.0points Find the direction of the resultant force (in re- lation to forward, with counterclockwise con- sidered positive). Answer in degrees from the positive x -axis, with counter-clockwise positive, within the limits of - 180 to 180 . Answer in units of . 004(part3of3)3.0points If the car has a mass of 3718 kg, what magni- tude of acceleration does it have?
