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...

The figure below shows a block of ice sliding down a frictionless ramp at an angle of 50 degrees while an ice worker pulls on the block (using a rope) with force Fr having a magnitude of 50 N and directed up the ramp. As the block slides down the ramp through a distance,? of 0.50 m, its kinetic energy increases by 80 Joules. What is the mass of the ice block

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...
