Question

c) it is impossible d) It is impossible to tell because the angular motion of the coins e) The coins hit at the same time. 2. For the coins in the previous question, which of the following statements is true concerning the speed with which the coins strike the ground. a) They both hit with a speed of zero. b) The coin that moves faster as it leaves the table will hit with the largest speed. c) The coin that moves slower as it leaves the table will hit with the largest speed. d) The answer will vary depending on the height of the table. e) The vertical velocities will be the same and hence so will the speeds. 3. An object is moving with constant velocity. According to Newton's Laws of Motion, this means that a) The net force acting on the object is zero b) The net force acting on the object is constant, but not zero. c) The acceleration of the object is 9.8 m/s^2 downward. d) None of the above statements is true. c) All of the above statements are true 4. You attach a rope to a ball and swing it around your head in a circle. What forces are acting on the ball? a) Normal, Tension, Weight b) Normal and Tension c) Tension, Weight, Centripetal 4) Tension and Weight e) Tension only

Explanation / Answer

The acceleration of an object is zero because velocity of an object is constant.

From Newton's second law, the net force acting on theobject is the product of mass and acceleration.

      F= ma

        =m (0)

        =0

So, the net force acting on the object is zero.

Hence, the correct option is (a).
