a) The angular velocity
?= v/r = 20/100 = 0.2rads-1
b) The centripetal force
Fc= m v2/r =(100*202)/100 = 400N
c) The centripetal acceleration
a= v2/r = 202/100 =4m/s2

(Solved)
An aluminium tray of mass 400g containing 300g of water is placed in a refrigerator. After 80 minutes, the
tray is removed and it is found that 60g of water remains unfrozen at 0^oC. If the initial temperature of the tray and its contents was 20^oC, determine the average amount of heat removed per minute by the refrigerator. Take s.h.c of aluminium = 900JKg-1K-1, s.h.c of water = 4200JKg-1K-1, s.l.h. of fusion of ice = 3.4*25JKg

(Solved)
In an experiment to determine the specific heat capacity of a metal, a 20g of the metal was transferred
from boiling water to a lagged copper calorimeter containing cold water. The water was stirred and a
final steady temperature was realized. The following data was recorded:
-initial temperature of cold water and calorimeter =20^oC
-temperature of boiling water =99^oC
-final temperature of water, calorimeter and metal =23.7^oC
-mass of cold water plus calorimeter =130g
mass of calorimeter =50g
Take s.h.c. of water=4200JKg-1K-1, s.h.c. of copper=400JKg-1K-1.
Use the data above to determine:

70g of a solid initially at 25^oC was carefully dropped into water in a calorimeter at 60^oC. If the final
constant temperature of the water and the solid was 54^oC and the mass of water is 500g, determine the
specific heat capacity of the solid. Assume the heat absorbed by the calorimeter to be negligible. Take the s.h.c. of water = 4200JKg-1K-1.
