an object near the earth's surface is in a state of free-fall. The object is experiencing a downward force of 170 n. What is the mass of the object?

When an object is under free fall then it means the net force on the object is only due to gravitational attraction force

So here we have


F_(net) = mg

so in order to find mass we can use


m = (F_(net))/(g)

here given that net force on the object is

F = 170 N


m = (170)/(9.8)


m = 17.35 kg

so the mass of the object must be 17.35 kg
