I can't do this task,
Calculate the speed the ball has after rolling up
against: h=0.5 m=0.028kg
The task consists of several parts but I can't get it right. A ball rolls up the hill and at the beginning of the hill it rolls down but there it was 0.6m high if that's relevant.

Loading...Hello, I wanted to ask if this reaction (Stopper is shown in brown.) can be said to occur in a closed system (if one considers the aqueous solution and the air inside the beaker as one system) or it can be said to occur in an open system (if one considers only the aqueous solution…
How do you convert an improper fraction (624/300) to a decimal? Using long division.
Hello, a bus braked, I braced myself against the force, then the bus accelerated, I was thrown backward and my head hit the window in the middle of the bus. Following question: The bus is accelerating faster, but my upper body isn't, and the partition wall is theoretically coming toward my head. Chat GPT says…
Hello dear community I would like to buy a KTM EXC 125. I really enjoy riding in the woods and off-road in general. I'd do about 40% on-road and 60% off-road. Now, my question is, do you really have to change the piston every 30 hours of operation? I'm not someone who rides on motocross…
Can someone explain this last step to me? The right-hand part is the derived logarithm. The simplification probably comes about somehow through the fraction. I just don't understand why this X-1 has to go at the end. Or rather, it has to go there, which makes sense from what I know so far. But it…
How do I solve such tasks? Does anyone have a study sheet?
below the body has kinetic energy. That’s what you thought.
Then it rolls up and part of this kinetic energy is consumed to perform lifting work.
Ekin(3) = Ekin(below) – Epot
ready.
Tip: Vkin before + vpot before = vkin after + vpot afterwards.
Your playback of the task sounds tricky.
That sounds like that.
