Answer:
12.83 m/s^(2)

Step-by-step explanation:

In this case we are talking about the centripetal acceleration
a_(c), which can be calculated by:


a_(c)=(V^(2))/(r)

Where:


V=112 (km)/(h) (1000 m)/(1 km) (1h)/(3600 s)=31.11 m/s is the speed of the motorcycle


r=75.4 m is the radius of the path the motorcycle is going around

Solving:


a_(c)=((31.11 m.s)^(2))/(75.4 m)

Finally:


a_(c)=12.83 m/s^(2)
