Question

A 19 kg box is given a shove across a horizontal surface that gives it an initial speed of 7 m/s. The box is eventually brought to rest by friction. The coefficient of kinetic friction in this example is 0.44. How far does the box go after the shove before it stops?

Answer #1

1.A 23 kg box is given a shove across a horizontal surface that
gives it an initial speed of 6 m/s. The box is eventually brought
to rest by friction. The coefficient of kinetic friction in this
example is 0.42. How far does the box go after the shove before it
stops?
??? m?
2. A 15 kg box is given a shove across a horizontal surface that
gives it an initial speed of 18 m/s. The box is eventually...

A 5.0 kg box slides down a 5.0 m high frictionless hill,
starting from rest, across a 2.0 m wide horizontal surface, then
hits a horizontal spring with spring constant 500 N/m. The ground
under the spring is frictionless, but the 2.0 m wide horizontal
surface is rough with a coefficient of kinetic friction of
0.25.

surface?

A 1 kg. box is given a push so that it slides across the floor.
How far will it go, given that the coefficient of kinetic friction
is 0.31 and the push imparts at initial speed of 3.1 m/s? Calculate
to one decimal. Use g = 9.8 m/s2

A 1 kg. box is given a push so that it slides across the floor.
How far will it go, given that the coefficient of kinetic friction
is 0.19 and the push imparts at initial speed of 5.4 m/s? Calculate
to one decimal. Use g = 9.8 m/s2

An object (m = 2.08 Kg) moving on a horizontal surface reaches
the bottom of an incline with a speed of 4.18 m/s. The incline
makes an angle of 37.0 degrees with respect to the horizontal. The
coefficient of kinetic friction between the box and the inclined
surface is 0.300. How far up the inline will the object move before
coming to stop?

The initial speed of a 2.58-kg box traveling up a plane inclined
37° to the horizontal is 4.55 m/s. The coefficient of kinetic
friction between the box and the plane is 0.30.
(a) How far along the incline does the box travel before coming to
a stop?
---m
(b) What is its speed when it has traveled half the distance found
in Part (a)?
---m/s

2. A 5.0 kg box is moving on a
horizontal surface at 0.50 m/s with a rope applying a constant
tension on the box of 100 N at an angle of 10° above the horizontal
(above the direction of motion). The coefficient of kinetic
friction between the box and the surface is 0.25. What is the speed
of the box after it has moved 25 cm?

A 4.5 kg box slides down a 4.8-m -high frictionless hill,
starting from rest, across a 2.0-m -wide horizontal surface, then
hits a horizontal spring with spring constant 520 N/m . The other
end of the spring is anchored against a wall. The ground under the
spring is frictionless, but the 2.0-m-long horizontal surface is
rough. The coefficient of kinetic friction of the box on this
surface is 0.24.

A 4.5 kg box slides down a 5.2-m -high frictionless hill,
starting from rest, across a 2.2-m -wide horizontal surface, then
hits a horizontal spring with spring constant 550 N/m . The other
end of the spring is anchored against a wall. The ground under the
spring is frictionless, but the 2.2-m-long horizontal surface is
rough. The coefficient of kinetic friction of the box on this
surface is 0.27.

A 4.5 kg box slides down a 5.2-m -high frictionless hill,
starting from rest, across a 1.6-m -wide horizontal surface, then
hits a horizontal spring with spring constant 540 N/m . The other
end of the spring is anchored against a wall. The ground under the
spring is frictionless, but the 1.6-m-long horizontal surface is
rough. The coefficient of kinetic friction of the box on this
surface is 0.27 What is the speed of the box just before reaching
