Question
An engineer is working on a new roller coaster, and he begins by making a scale model. On this model, a car of total mass 0.50 kg
moves with negligible friction along the track shown in the figure. The car is given an initial speed vo = 1.5 m/s at the top of the first
hill of height 2.0 m. Point A is located at a height of 1.9 mat the top of the second hill, the upper part of which is a circular arc of
radius 0.95 m.
0.50 kg
- U% = 1.5 m/s
r= 0.95 m
2.0 m
1.9 m
Calculate the speed of the car at point A.
A 1.25 m/s
B) 2.05 m/s
(c) 3.06 m/s
D) 4.23 m/s
