 A space ship with a dead engine in remote outer space continues moving  a) because some kind of force acts on itb) in a curved pathc) even though no net force acts on itd) due to gravity  Which of the following best describes when Newton's 1st Law is true? a) when there is no air resistance b) when there is no friction c)when there is no air resistance and there is no friction d) always  A 20kg bicycle is traveling on a straight flat road at a speed of 10m/s. What is the net force on the bicylce?  a) 0 Nb) 10 Nc) 20 Nd) 30 Ne) 200 N Suppose you push with a 200 N of force agianst your 1500-N refrigerator and it slides across your kitchen floor in a straight line at a constant speed. The friction force of the the floor against the refrigeratr must be  a) zero b) 200 N c) 1300 Nd) 1500 Ne) greater than 1500 N  ...and the force with which you push must be  a) equal and oppositely directed to the friction force b) the action force, and the friction the reaction force c) both of thesed) none of these  I throw an apple into the air at 30 m/s. At the top of its trajectory, its acceleration is  a) 0 m/s^2 b) 5 m/s^2c) 10 m/s^2d) 20 m/s^2e) 45 m/s^2 A car increases its speed from 60 to 65 miles per hour in the same time that a bicycle increases its speed from 0 to 5 mph. In this case the acceleration is greater for the  a) car b) bicyle c) ...it is the same for each Authortashaluth ID189573 Card SetPhysicsFinal Descriptionjnkjn Updated2012-12-16T07:57:29Z Show Answers
