AI Thread Summary
To hit a target 140 m away with a bullet traveling at 240 m/s, the bullet's drop due to gravity must be calculated. The time the bullet is in the air can be determined using the formula for horizontal motion. Once the time is known, the vertical drop can be calculated using the equation for free fall. To ensure the bullet hits the target, the gun must be aimed at an angle that compensates for this drop. Understanding these principles is essential for accurate shooting.

A hunter aims directly at a target (on the same level) 140 m away.

a. if the bullet leaves the gun at a speed of 240m/s, by how much will it miss the target?

b. At what angle should the gun be aimed to hit the target?

could someone please help us figure out which equations to use to solve a and b? that would be wonderful because we have tried all we know and can't find the correct answer.

Try to picture what is going on. The bullet has no vertical velocity so you can just imagine that it's dropped from a certain height. If you knew how long the bullet was in the air for, you could find out how far it fell in that time.

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'

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...
