Kinetic Energy and the Power of Human Climbing

AI Thread Summary
To calculate the height a person climbs from the third stair up, multiply the individual step height (0.16m) by the number of steps climbed (12), resulting in a height of 1.92m. To find the average power exerted while climbing, use the formula Power = Work/Time, where Work is the gravitational potential energy gained (mass x gravity x height) and time is 2.9 seconds. The assumption made about each climber's kinetic energy is that it is converted entirely into potential energy during the climb. This analysis highlights the relationship between kinetic energy, potential energy, and the power exerted in climbing. Understanding these principles can enhance insights into human physical performance in climbing activities.

How to calculate the height of a person climbs from the third stair up? i don'[y know how to calculate it. HELP!

I have the mass=68kg, individual step height=0.16m, number of steps in flight=12

additional question: calculate the average power each person exerted while climbed the stairs.
i have the time= 2.9s for its average seconds.. Help!

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
