The net force on the rope is C A)20N andrope tension isals.50N. zero and rope tension is 50 N. D)zero and rope tension is also zero 10) ,60 A package falls off a truck that is moving at 30 m/s. Neglecting air resistance, the horizontal speed of the package just before it hits the groundis A) zero. B) less than 30 m/'s but more than zero. about 30 m/s. D) more than 30 m/s 15. A roller-coaster ride with 6 passengers takes 3 minutes. Neglecting friction, a similar ride with 12 passengers aboard would take A) 1.5 minutes B) 3 minutes. C) 6 minutes. D) 18 minutes. 16, When you flick a card from beneath a coin that hardly moves, you're illustrating B) equilibrium. C) support force. D) friction. Galileo's interpretation of motion differed from Aristotle's in that Galileo emphasized 4 the acceleration of free fall. ates of time 8) e role of distance in describing motion. D) none of the above Galileo's use of inclined planes allowed him to effectively A) slow down the ball's changes in speed. B) reduce the time of the ball's changes in speed. C) eliminate all changes in speed. D eliminate friction. Inertia is defined as a A) force. B) property of matter. C ©change in motion. D) none of the above

Explanation / Answer

(13) The force on the rope is zero and tension is 50N.

(14) The speed will be almost equal to 30m/s.

(15) A similar ride would also take 3 minutes.

(16) That is an example of an illustration of inertia.
