Homework Statement
a skater moves from point A to C in a circulaire path as shown in the picture
C is the end of the circular path
find R the force that the ground exerts on the skater at point C using Newten's second law
there is no friction nor air resistance
Homework Equations
p-R=ma
The Attempt at a Solution
well I did this
p-R=0
so that P=R
am I right ? cause I think in point "C" there is no acceleration
