Using the formula W=mg, where W is weight, m is mass and g is gravitational acceleration, we can calculate the weight of the object.
W = mg = (20 kg)(4 m/s^2) = 80 N
Therefore, the correct answer is option a) 80 N.
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
80 N
b
0.2 N
c
5 N
d
200 N
