Battery Energy and Altitude Change

AI Thread Summary
An electric scooter's battery provides 120 Wh of energy, but due to friction and other losses, only 40% of that energy is usable for altitude change. With a combined weight of 890 N for the rider and scooter, the effective energy available for elevation gain is 48 Wh. To determine the altitude change, the relationship between energy, weight, and gravitational potential energy must be applied. Clarification on relevant equations and concepts is requested to facilitate understanding of the problem. The discussion emphasizes the need for guidance on how to approach the calculations involved.

Homework Statement



An electric scooter has a battery capable of supplying 120 Wh of energy. If friction forces and other losses acount for 60.0% of energy usage, what altitude change can a rider achieve when driving in hilly terrain, if the rider and scooter have a combined weight of 890N.

Any equations or anything that may make it clear to me would be appreciated. I am capable of solving it for myself, so it is not necessary to actually do the problem. Thank you!
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
