The mass of the sled and its two riders in Figure 5.5 is 243 kg. Find the magnitude of the centripetal force that acts on the sled during the turn with a radius of (a) 33.0 m and (b) 24.0 m.

Answer 1

I was able to solve this question:
so, Fc=mv^2/r
I had mass=243Kg
radius1=33
radius2=24
velocity=34m/s
a)243*(34)^2/33=8512.36N
b)243*(34)^2/24=11704.5N

Answer 2

Was velocity given in the figure?

Answer 3

Yes, sorry forgot to mention it.
