Hello. I am trying to learn physics on my own. I have always thought it was a neat thing.
I am wondering if you could show me how to do these solutions. I can't figure it out.
#1 A cyclist (total mass of 68kg including the bike) traveling initially at 6.5m/s slams on the brakes and skids to a stop in 9.4m. The coefficient of kinetic friction between the tires and the trail is 0.93
a) Calculate the magnitude of the force of kinetic friction
b) Calculate the work done by the force of friction during the skid
#2 A roast in a refrigerators freezer compartment has a potential energy of 35J relative to the floor if the roast is 1.7m above the ground what is the mass of the roast?
Thanks
