A block (6 kg) starts from rest and slides down a frictionless ramp #1 of height 6 m. The block then slides a horizontal distance of 1 m on a rough surface with kinetic coefficient of friction μk = 0.5. Next, it slides back up another frictionless ramp #2. Find the following numerical energy values: 1.Initial gravitational potential energy on Ramp #1: U1G = J 2.Kinetic energy at bottom of Ramp #1 before traveling across the rough surface: K =...

As shown below (not to scale), a block of mass starts from rest
and slides down a frictionless ramp of height h. Upon reaching the
bottom of the ramp, it continues to slide across a flat
frictionless surface. It then crosses a "rough patch" on the
surface of length d=10m. This rough patch has a coefficient of
kinetic friction uK=.1. After crossing the rough patch, the block's
final speed is vf=2m/s. What is the height of the ramp? Hint: I...

The figure(Figure 1) shows a 1.75-kg block at rest on a ramp of
height h. When the block is released, it slides without friction to
the bottom of the ramp, and then continues across a surface that is
frictionless except for a rough patch of width 10.0 cm that has a
coefficient of kinetic friction 0.650. Part A Find h such that the
block's speed after crossing the rough patch is 3.40 m/s .

1. A block of mass m = 0.23 kg slides with initial velocity
v0 = 1.4 m/s along a frictionless surface (as in the
figure). The block next slides through a region of length d = 0.25
m with kinetic friction. After passing through the friction region,
the block slides up a curved ramp until momentarily coming to rest
at a height h above the level surface. If the kinetic friction
coefficient μ k = 0.204, what height h does...

As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...

Problem 4 A block of mass m slides at velocity vo across a horizontal frictionless surface toward a large curved movable ramp n and has a smooth circular frictionless face up which the block can easily slide. When the block slides up the ramp, it momentarily reaches a maximum height a shown in Figure II, and then slides back down the frictionless surface as shown in Figure III. face to the horizontal (a) Find the velocity of the ramp at...

What is the conceptual and mathematical methods for solving this
problem?
A moving 5.00 kg block collides with a horizontal spring whose spring constant is 468 N/m. The block compresses the spring a maximum distance of 2.50 cm from its rest position. The coefficient of kinetic friction between the block and the horizontal surface is 0.320. What is the work done by the spring in bringing the block to rest? -1.46x10-1 J Computer's answer now shown above. Submission not graded....

PHYS1030 Newtonian Mechanks QUESTION #10: A 22-kg block is held a rest against a spring of force constant k # 930 N/m as shown below. Initially the spring is compressed a distance of 15 em. When the block is released, it slides across a surface that is frictionless except for a rough patch of width 60.0 cm that has a coefficient of kinetic friction μ.-0.34. Find the block's speed (m/s): (a) before crossing the rough patch b)after crossing the rough...
