What is the force in units of newtons of a 40 pound object?

a) 176 N

b) 9.1 N

c) 4.0 N

d) 400 N

There's 2.2 pounds in a kg.

1 kg = 2.2 kg

x kg = 40 pounds.

2.2 x = 40

x = 40 / 2.2

x = 18.2 kg

Now you need to change 18.2 kg into Newtons.

F = m * g

g = 9.81

m = 18.2

F = 18.2 * 9.81

F = 178 N

You should pick A. Who knows how and when things were rounded.

The answer to this Is A
