An object is released from rest on a planet that has no atmosphere. The object falls freely for 5.02 m in the ﬁrst second. What is the magnitude of the acceleration due to gravity on the planet?

can someone help me please? i tried doing this
-5.02m =Xa
-5.02m =Vo*(t) + (1/2)*a(t^2)
-5.02m =(1/2)*a
-10.04m/s^2 = a
