Ice of mass 48.0 g at -9.8° C is added to 204 g of water at 15.1° C in a 109 g glass container of specific heat 0.200cal/g-°C at an initial temperature of 25.7° C. Discover the final temperature of the system.
In the Atwood machine shown below, m1 = 2.00 kg and m2 = 5.35 kg. The masses of the pulley and string are negligible by comparison. The pulley turns without friction and the string does not stretch. The lighter object is released with a sharp push th..
