Transcribed Image Text:35 The bottom of a heavy block is covered with
sandpaper. The block is repeatedly slid 1.0 meter
at constant speed across a uniform, horizontal
wooden plank by the application of a constant
horizontal force. As the coefficient of friction
between the sandpaper and the plank decreases,
the amount of work done in sliding the block
1.0 meter along the plank at constant speed
(1) decreases
(2) increases
(3) remains the same

Transcribed Image Text:33 A stone is dropped in air from a height of
50 meters above the ground. As the stone falls,
what happens to the stone's kinetic energy and
internal energy?
(1) Kinetic energy decreases and internal
energy decreases.
(2) Kinetic energy decreases and internal
energy increases.
(3) Kinetic energy increases and internal
energy decreases.
(4) Kinetic energy increases and internal
energy increases.
34 An aluminum pie pan is attached to a string and
suspended from a hook, as shown in the diagram
below. The pan is released from position A and
swings through the air to position B.
Aluminum

What is the relationship between the kinetic
energy at position B, KEg, and the gravitational
potential energy at position A, PE,with respect
to B?
(1) KE, is equal to PE, minus
against friction.
(2) KE, is equal to the PEA plus work done
against friction.
(3) KE, is equal to PEĄ-
(4) KEg is equal to 2PE4.
