Physics problem help please!?
A 30kg child rides on a ferris wheel that takes her on a vertical circular path. The radius of the wheel is 20m, and 1 revolution takes 22 seconds. What is the magnitude of the resultant force on the child at the highest point of the ride?
Choices are:
A. 49N
B. .29kN
C. .34kN
D. .25kN
Comments
A.49N
Centripetal force = mass x velocity2 / radius
Velocity =30* 2 * pi * 20 /22(r) ^2 / 20 = 48.94 N

the galaxies rotate at speeds inconsistent with their obvious mass is seeing that we do see it all. I am relating to it as being the theoretical Dark Matter. There are very robust proofs that shows that darkish subject exist. One the is the inconsistent velocity of and obvious mass. darkish subject makes up approximately seventy five% to eighty% of the problem within the Universe...
