A block of mass m is at rest at the top of a ramp of vertical height h. The block starts to slide down the frictionless ramp and reaches a speed v at the bottom. If the same block were to reach a speed 2v at the bottom, it would need to slide down a frictionless ramp of vertical height _____.

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...

A 2.30 kg block slides down a 16.0 m long ramp that makes an angle of 55.0degree with the horizontal. It starts at rest. (a) What is the block's speed at the bottom of the ramp? Use conservation of energy to find your answer. (b) The block collides and sticks to another block at rest that has 4 times its mass. What is the speed of the combined blocks? (c) A force stops the combined masses in a distance of...

A block is placed on a frictionless ramp at a height hof 14.5 m above the ground. Starting from rest, the block slides down the ramp. At the bottom of the ramp, the block slides onto a frictionless horizontal track without slowing down. At the end of the horizontal track, the block slides smoothly onto a second frictionless ramp. 0 = 48.3° By = 25.5 How far along the second ramp does the block travel before coming to a momentary...
A block of mass m slides down a frictionless ramp to a loop of radius R,...
A block of mass m slides down a frictionless ramp to a
loop of radius R, also frictionless. It's initial height
above the bottom of the loop is ?h = 3R and the
block starts at rest.
What is the magnitude of the normal force that the track of the
loop exerts on the block at position 2? You can assume that the
block is exactly at the horizontal height of the center of the loop
when it reaches position...

A block starts from rest and slides down a smooth ramp of height h. When it reaches the bottom it is moving at speed v. It then continues to slide up a second smooth ramp. What is the velocity up the second ramp at the point the potential energy is equal to the kinetic energy? 1. v/2 2. v/3 3. v/4 4. v 5. sqrt(3)v/ 6. sqrt(2)v/

Please show all work! A block of mass 237 g compresses a spring with a spring constant of k = 520. N/m a distance of 10.0 cm. The block is released. It travels across a frictionless surface and up a ramp where it comes to a stop. a) What is the energy stored in the spring? b) Use conservation of energy to determine how high the block goes. c) If the ramp is inclined 30.0◦, what is the distance it...

A block of mass 3.5 kg is sitting on a frictionless ramp with a
spring at the bottom that has a spring constant of 435 N/m (refer
to the figure). The angle of the ramp with respect to the
horizontal is 29°. show answer Incorrect Answer 33% Part (a) The
block, starting from rest, slides down the ramp a distance 52 cm
before hitting the spring. How far, in centimeters, is the spring
compressed as the block comes to momentary...

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 =...
