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
To find the weight of a 15 kg mass on Earth, we can use the formula:
Weight in Newtons = Mass x acceleration of gravity
First, let's calculate the weight in Newtons:
Weight in Newtons = 15 kg x 9.8 m/s^2
Weight in Newtons = 147 N
To convert this weight from Newtons to pounds force (Lbf), we can use the conversion factor of 0.224 N/Lbf.
Weight in pounds force (Lbf) = Weight in Newtons x 0.224 N/Lbf
Weight in pounds force (Lbf) = 147 N x 0.224 N/Lbf
Weight in pounds force (Lbf) = 32.85 Lbf
So, a 15 kg mass weighs approximately 147 Newtons or 32.85 pounds force (Lbf) on Earth.
