find the average power pavg created by the force f in terms of the average speed vavg of the sled.
A sled of mass
is being pulled horizontally by a constant upward force of magnitude
that makes an angle
with the direction of motion. The coefficient of kinetic friction is
. The average velocity of the sled is
.
Part D
Find the average power
created by force
.
Express your answer in terms of
,
, and
.

Let us now consider several questions that include numeric data.
A sled is being pulled along a horizontal surface by a horizontal force
of magnitude 600 N. Starting from rest, the sled speeds up with acceleration 0.08
for 1 minute.
Part E
Find the average power
created by force
.
Express your answer in watts to three significant figures.
