Physics 221 Test #2 Summer Session I Part 1 Multiple Choice:Circle the correct answer.1) Newton's first law of motion, that objects tend to keep doing what theyare already doing, is also known as A) the Law of Falling Bodies B) the Law of InertiaC) the Law of ReactionD) the Law of Averages2) What's the weight of 5kg mass?3) What's the mass of a 3200lbs automobile?4) During a test in a sports equipment lab, a 150g golf ball is accelerated at 120m/s2. The force required to do this is 5) A rocket sled used in old Air Force test, could produce 380,000N of thrust horizontally and acted on a 2500kg mass. The resulting acceleration isA) 1.52m/s2B) 152m/s2C) 9.5 x 102m/s2D) 32m/s26) An 80lbs box is resting on a level surface and the coefficient of staticfriction is 0.75. The force required to get the box moving is
