Question

A small block has constant acceleration as it slides down a frictionless incline. The block is released from rest at the top of the incline, and its speed after it has traveled 7.00 mm to the bottom of the incline is 3.80 m/s . What is the speed of the block when it is 3.00 mm from the top of the incline?

A block of mass 13.0 kg slides from rest down a frictionless
39.0° incline and is stopped by a strong spring with
k = 2.70 ✕ 104 N/m. The block slides
3.00 m from the point of release to the point where it comes to
rest against the spring. When the block comes to rest, how far has
the spring been compressed?
m

1.A small block of mass 3.5 kg starting from rest slides down on
an incline plane of height 2.0 m, 40 degrees with respect to
horizontal (Fig. 2). The coefficient of kinetic friction between
the block and the incline plane is 0.25. At the end of the incline
plane, the block hits the top of a hemispherical mound of ice
(radius 1.0 m) , loses 75% of final kinetic energy (KE=0.5mv*v)
before the collision, then slide down on the surface...

A small block travels up a frictionless incline that is at an
angle of 30.0° above the horizontal. The block has speed 4.15 m/s
at the bottom of the incline. Assume g = 9.80 m/s2. How far up the
incline (measured parallel to the surface of the incline) does the
block travel before it starts to slide back down?

A block of mass m = 2.10 kg slides down a 30.0∘ incline which is
3.60 m high. At the bottom, it strikes a block of mass M = 8.00 kg
which is at rest on a horizontal surface (Figure 1). (Assume a
smooth transition at the bottom of the incline.) The collision is
elastic, and friction can be ignored. Determine the speed of the
block with mass m = 2.10 kg after the collision. Determine the
speed of the...

A 9.31 kg block is placed at the top of a frictionless inclined
plane angled at 14.9 degrees relative to the horizontal. When
released (from rest), the block slides down the full 2.77 meter
length of the incline. Calculate the speed (magnitude of the
velocity) of the block at the bottom of the incline. [Start by
drawing a free-body diagram for the block.] Note that all the
information provided may not be necessary to solve the problem.

Name:__________________________________________Section____
A block of mass ? = 12.0 kg is released from rest on an incline
angled at θ = 30 degrees. The block slides down and incline of
length ? = 1.40 m along the incline, which has a coefficient of
kinetic friction between the incline and the block of ?? = 0.180.
The block then slides on a horizontal frictionless surface until it
encounters a spring with a spring constant of ? = 205 N/m. Refer to
