1)What is the amount of force required to keep a 6-kg object that is in outer space moving with a constant velocity of 2 m/s is _N. a. 0.333 b. 2 C. 3 d, 6 e, 12 f. none 2) The acceleration of an object is related to the net force exerted upon it and related to the mass of the object. In equation form: a = Fnet / m. a. directly, inversely b. Inversely, directly c. directly, directly d. inversely, inversely 3) Use Newton's second law to predict the effect of an alteration in mass or net force upon the acceleration of an object. a. An object is accelerating at a rate of 8 m/s' when it suddenly has the net force exerted upon increased by a factor of 2. The new acceleration will be_ An object is accelerating at a rate of 8 m /s' when it suddenly has the net force exerted upon increased by a factor of 4. The new acceleration will be_ m/s'. An object is accelerating ex a rate of 8 m/s' when it suddenly has its mass decreased by a factor of 4. The new acceleration will be m/s'. An object is accelerating at a rate of 8 m /s' when it suddenly has the net force exerted upon increased by a factor of 2 and its mass decreased by a factor of 4. The new acceleration will be m/ s. These force diagrams depict the magnitudes and directions of the forces acting upon four objects, In each case, the down force Is the force of gravity, Rank these objects In order of their acceleration, from largest to smallest: Object A Object B Object C Object D 150 N 150 N $ 50 N 1 50 N 20 N 50 N 50 N 10 N 40 N 15 N 50 N 150 N 50 N 150 N A free-body diagrams show all the individual forces acting upon an object. The net force is the vector sum of all these forces (EF). Determine the net force and state if there is an acceleration -20 N Pair-ON Ffxict -10 N -25 N EF -_ Accel'n? Yes or No Accel'n? Yes or No Accel'n? Yes or No 6) In a grocery store, you push a 12.5kg shopping cart with a force of 14 N. If the cart starts at rest, how far does it move in 3 seconds? 7)A catcher stops a 92 mi/hr (41.1 m/s) pitch in his glove, bringing it to rest in 0.15m. If the force exerted by the catcher is 803 N, what is the mass of the ball? 1869 12
