What does a 15 kg mass weigh on Earth? need assistance in setting up problem to get answer in Newtons and in pounds.

thanks

Weight in Newtons = M g

=(Mass in kg) x (acceleration of gravity in m/s^2)

The acceleration of gravity on Earth is g = 9.8 m/s^2. Do the multiplication

To convert the answer from Newtons to Lbf (pounds force), use the conversion factor 0.224 N/Lbf
