A55.0-g sample of hot metal initially at 99.5oc was added to 40.0 g of water in a styrofoam coffee cup calorimeter. the water and calorimeter were initially at 21.0oc. if the final temperature of mixture was 30.5oc, calculate the specific heat capacity of the metal. the specific heat of water is 4.184 j/(g. oc) and heat capacity of calorimeter is 10.0 j/oc.

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

An object with initial temperature 130 â f is submerged in large tank of water whose temperature is 50 â f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = â 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
