Falling Force

AI Thread Summary

The discussion centers on calculating the resultant force acting on a parachuter with a mass of 75 kg falling at a constant speed of 25 m/s. The relevant equation used is F = ma, where 'm' is mass and 'a' is acceleration. Since the parachuter is falling at a constant speed, the net force is zero, leading to the conclusion that the correct answer is (d) No net force. Participants confirm this understanding, reinforcing the concept that constant velocity indicates balanced forces. The discussion effectively clarifies the relationship between speed, mass, and resultant force in this scenario.

Homework Statement

A parachuter of mass 75 kg falls towards the Earth at a speed of 25 ms^-1. What is the resultant force acting on the person?

a. 750 N
b. 450 N
c. 1,350 N
d. No net force
e. 1,500 N

Homework Equations

F = ma

The Attempt at a Solution

I think the answer is (d) because 25 ms^-1 is constant speed. Am I right?

Thanks

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 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

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...
