How do I solve these physics problems?
Even with the solution formulas, I can't figure out how these two problems work. I would greatly appreciate some help. For task 4 (first picture): You have to work with potential energy, kinetic energy and static friction, if I understood correctly. I've noticed that I generally have trouble with tasks that involve frictional forces. Thank…
Inclined plane, static and sliding friction, how to determine?
Shouldn't 25° be used here for mH (coefficient of static friction) instead of mG (coefficient of sliding friction), since from 35° the coin starts to slide and at 25° the coin sticks?
[Physics] Fairground physics: Rotor/carousel?
Good evening, is my completed task a) wrong? The static friction force Fhr and the weight force Fg balance each other out if the passenger shown here is pressed against the inner wall of the cylinder and does not slide down. Then only the centripetal force Fzp acts on the passenger shown here. However, the…
