Avery slippery block of ice slides down a smooth ramp tilted at angle ? the ice is released from rest at vertical height h above the bottom of the ramp.

a)find an expression for the speed of the ice at the bottom?

b)evaluate your answer to part a for ice released at a height of 22cm on ramp tilted at 40 ? ?

Part 1

Here as we know by energy conservation

Initial potential energy + initial kinetic energy = final potential energy + final kinetic energy

now we will have

now we will plug in all data into the equation

so we will have

from above equation now

Part b)

as we know that

now from the above equation

gans

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.
