Part A A car coasts at a constant speed over a circular hill as shown in (Figure 1). Which of the free-body diagrams in the figure is correct? Explain. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. Reset Help A The car is traveling along a circle and so it must have centripetal acceleration which points C upward From Newton's second law, if an object is accelerating downward, the total force on the object must be B downward The answer is because only there is the force (the weight of the car) greater than the force (the normal force on the car) so that the total force is Figure A. B. C
