1.) A
horizontal force is used to
|
|
pull a 2.0kg
cart at constant
|
|
|
speed of 5.0m/s
across a
|
|
|
tabletop. The
force of friction
|
|
|
between the cart
and the
|
|
|
tabletop is 10N.
What is the
|
|
|
coefficient of
friction between
|
|
|
the cart and the
tabletop? Is
|
|
|
the friction
force kinetic or
|
|
|
static? Why?
