Asmall ice flakewith a mass of 0.1 kg is released from rest at point a. when it reaches point bat the bottom of the hemispherical bowl the ice flakeis observed to have a speed of 1.8 m/s. calculate the work done by friction on the ice flakewhen it moves from ato b.

that would be b i just took the test : )

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
