i know cause i already learned this
It would be hard so many factors play a role in this angle kinetic potential energy gravity positioning height weight etc.to keep something as described moving as long as possible you'd have to build it heavily enough to balance out the momentum at each climax of the swing to balance with the gravitational pull of the earth core.I'd use a material such as copper for the variable.Also the weight distribution on the variables base plays a role.Take all the into account and experiment for a while!maybe one day you could find the right proportions in every role for kinetic potential gravitational momentum and weight to keep it going forever. As said alotta factors play a huge role in this experiment <span />
Explanation:
can i get the crown please now hehehh ahhhahah hoohoh
they have a pictures just click and thats the answer ↑
Answer:26.65 kJ
Explanation:
Given
mass of skier=70 kg
length of ramp=62.5 m
slope
speed=3.77 m/s
so net force on skier must be zero
Net work done will be change in Potential energy of skier
Potential Energy
P.E.=26.65 kJ
