If an object has a mass of 20 kg on a planet with a force of gravity of 4 m/s2. What is the object's weight? **Remember** W=mg a 200 N b 5 N c 0.2 N d 80 N

The weight (W) of an object is given by the formula W = mg, where m is the mass of the object and g is the acceleration due to gravity.

In this case, the mass (m) of the object is 20 kg and the acceleration due to gravity (g) is 4 m/s^2.

So, using the formula W = mg, we can substitute the values:

W = 20 kg * 4 m/s^2

W = 80 N

Therefore, the object's weight is 80 N.

The correct answer is (d) 80 N.
