quizzes/429395/take Question 26 A 500 kg roller coaster car starts from rest at the top of a 80 m drop. Neglect friction and air resistance (except for question 27). Questions 23-27 refer to this situation. When the car's speed is 35 m/s, it is at a height (relative to ground level) of: Between 40 m and 60 m Less than 20 m More than 60 m Between 20 m and 40 m Question 27 A 500 kg roller coaster car starts from rest at the top of a 80 m drop. Neglect friction and air resistance (except for question 27). Questions 23-27 refer to this situation. If friction and air resistance do a total amount of work of -125,000 J, the speed of the car at the bottom of the ride is: Greater than 45 m/s Between 30 and 45 m/s Less than 15 m/s Between 15 and 30 m/s 1 pts 1 pts
