Question

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?

Answer 1

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
