How do you calculate the average frictional force during sliding?
F=ma Force = mass * acceleration The only force that acts on the child is his weight Contrabalacing this force is the frictional force You need to separate the gravity G=m*g in 2 forces and take only the componend that is paralel with the frictional force but in opposite direction. I cannot give you the entire solution here because i need to do a drawing. Hope it helped.
