Question

A cart with a mass of 5.0 kg is moving on a horizontal surface with a speed of 4.0 m/s. The cart then begins to roll up a hill. If you assume no friction, how high up the hill will the cart travel before coming to a stop?

Answer #1

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?

A cart of mass m1 = 8.8 kg, moving on frictionless
surface with a speed of 2.5 m/s makes an elastic collision with a
cart of unknown mass m2 moving at an unknown speed
toward m1 . After the collision, the 8.8 kg cart recoils
with a speed of 9.2 m/s as shown in the figure but now
m2 is at rest. Find the mass of m2.

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 cart with a mass of 2.0 kg is given quick push up a ramp so
that it starts with a speed of 3.0 m/s. Angle of the ramp is 30
degrees.
Friction can be ignored.
• What’s value of the forces that act on the cart? •
What is the net force and acceleration of the cart? •
What distance along the ramp does the cart travel before coming
to a stop?

Two low-friction physics demo carts collide on a horizontal
track. The first cart, with a mass of 0.150 kg , is moving to the
right with a speed of 0.800 m/s . The second cart, with a mass of
0.298 kg , is moving to the left with a speed of 2.27 m/s . The
carts collide in an elastic collision, such that the total klinetic
energy after the collsion is equal to the total kinetic energy
before the collision....

Two identical solid disks of unknown mass are moving on
horizontal surfaces. The center of mass of each disk has the same
linear speed of 8.5 m/s. One of the disks is rolling without
slipping, and the other is sliding along a frictionless surface
without rolling. Each disk then encounters an inclined plane 15°
above the horizontal. One continues to roll up the incline without
slipping while the other continues to slide up, again without
friction. Eventually, they come to...

A mass m = 13 kg is pulled along a horizontal floor, with a
coefficient of kinetic friction μk = 0.07, for a
distance d = 5.1 m. Then the mass is continued to be pulled up a
frictionless incline that makes an angle θ = 33° with the
horizontal. The entire time the massless rope used to pull the
block is pulled parallel to the incline at an angle of θ = 33°
(thus on the incline it is...

A sphere of mass 2.28 kg and radius 8.11 cm is moving on a flat
surface at a constant speed of 14.9 m/s. If the surface turns to a
ramp, how high will the sphere roll?

A mass m = 12 kg is pulled along a horizontal floor with NO
friction for a distance d =7.2 m. Then the mass is pulled up an
incline that makes an angle θ = 30° with the horizontal and has a
coefficient of kinetic friction μk = 0.49. The entire
time the massless rope used to pull the block is pulled parallel to
the incline at an angle of θ = 30° (thus on the incline it is
parallel...
