Draw a free body diagram of a 100 kg skater moving across frictionless ice. Calculate the weight of the skater.

Question

turingtest · Answer

in general$$F=ma$$weight is a result of the force of gravity, and the acceleration on an object due to gravity is labeled "g"$$weight=F_g=mg$$$$m=100kg$$$$g\approx9.8m/{s^2}$$so you can use those numbers to answer your question. In your free body diagram you will only have to label the force of gravity on the object (weight), and the normal force (that is the force of the surface that is equal and opposite to the force of gravity, which keeps the object from accelerating downwards as is stated by Newton's third law) We are told to ignore friction, so it will look like this:|dw:1324586795381:dw|
