Answer:
43.46 m/[tex]s^{2}[/tex]
Explanation:
Two forces will be acting on her at the bottom point of the rollar coaster,
One will be mg (vertically downwards) Â and other will be ma(vertrically upwards) due to the centripetal force .
So, taking the resultant of the forces , we will get
ma-mg = 1750 (Given)
m(a-g) = Â 1750
52(a-g) = 1750
a-9.81 = 33.65
a = 43.46
