In this question, we use the formula for the centripetal force:
 11ec0fda_997e_be25_a67f_771a007934bc_NR0004_00 F = centripetal force
m = mass
V = velocity
r = radius of the circular path
STEP 1. Convert the velocity from km/h to m/s:
 11ec0fda_997e_be26_a67f_8dab850d1d68_NR0004_00 STEP 2. Fill in the values:
 11ec0fda_997e_be27_a67f_75119c4bd911_NR0004_00 F = 5,602 N
