In this question, we use the formula for the centripetal acceleration;
 11ec0fda_9981_081c_a67f_cddd239368d5_NR0004_00 a = centripetal acceleration
v = velocity
r = radius of the circular path
STEP 1. Convert the velocity from km/h to m/s;
 11ec0fda_9981_081d_a67f_a73748ea80d3_NR0004_00 STEP 2. Fill in the values;
