To treat a burn on his hand, a person decides to place an ice cube on the burned skin. the mass of the ice cube is 16.4 g, and its initial temperature is −13.6 ∘c. the water resulting from the melted ice reaches the temperature of his skin, 31.7 ∘c. how much heat is absorbed by the ice cube and resulting water? assume that all of the water remains in the hand. constants for water can be found in this

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
