Calculate

i) The energy used in overcoming the friction during the child's descent

ii) The magnitude of the frictional force.

Totally confused about this question. I know Work done = Force.displacement in the direction of the force but then does this mean that question i) is equal to W=26(9.8)Cos19.47?

I have no idea. Would appreciate any help.

thank you
