You have two cups, one with m1 = 0.92 kg of water at t1 = 29.76oC and the other with m2 = 2.88 kg at t2 = 45.6oC. You mix the two in an insulated thermos. What is the final temperature of the water?
Homework Answers
Heat gained= Heat lost
m1*s*(T-t1)=m2*s*(t2-T)
0.92*(T-29.76)=2.88*(45.6-T)
T=41.77in degree celsius

Two objects of masses m1 = 0.44 kg and m2 = 0.92 kg are placed on a horizontal frictionless surface and a compressed spring of force constant k = 250 N/m is placed between them as in figure (a). Neglect the mass of the spring. The spring is not attached to either object and is compressed a distance of 9.0 cm. If the objects are released from rest, find the final velocity of each object as shown in figure (b)....
