## Physics (10th Edition)

(a) $F_c=12250N$ (b) $F_c=16800N$
From the results of Example 3, - Along the curve with $r=33m$: $a_c=35m/s^2$ - Along the curve with $r=24m$: $a_c=48m/s^2$ We also know that the total mass of the sled and 2 riders $m=350kg$. With that, the magnitude of $F_c$ acting on the sled is: - During the turn with $r=33m$: $F_c=ma_c=12250N$ - During the turn with $r=24m$: $F_c=ma_c=16800N$
