The maximum speed with which a 1700 kg horse makes a 180-degree turn is 12 m/s. The radius of the circle through
which the horse is turning is 30 meters. Determine the force of friction acting on the horse as it makes this turn.
a. 20400 N
b. 13981.94 N
c. 680 N
d. 8160 N
When making a 180-degree turn with a radius of 15 meters, a 900 kg car experiences a coefficient of friction of 0.60
