a piece of copper weighing 300g is heated to 100°c and is then quickly transferred into a copper calorimeter of mass 10g containing 100g of liquid with unknown specific heat capacity. if the final temperature of the mixture is 40°c calculate the specific heat capacity of the liquid (room temparature is 10°c) (specific heat capacity of copper is 400jkg/1​

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
