What is the Normal Force on a 16.2 kg Object Being Pulled with 10.2N Force?
Question: A 16.2 kg object is pulled along a frictionless horizontal surface by a horizontal net force of 10.2N. What is the normal force acting on the object? Answer: Fn= 16.2*9.8 =158.8 I am sure do i have to ignore the 10.2N force... Thank you for helping- blue__boy
