A 0.200 kg mass of metal with a specific heat capacity of 126 J/kg °C and an initial temperature of 90.0°C is placed in a 0.500 kg calorimeter at an initial temperature of 20.0°C with a specific heat capacity of 386 J/kg•°C. The calorimeter is filled with 0.100 kg of water with an initial temperature of 20.0°C. When the combination of the metal, the calorimeter, and the water reaches equilibrium, what is the final temperature? ce.. = 4200 J/kg•°C)

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
