Projectile Motion Calculations for a Shell Fired at 30 Degrees

AI Thread Summary
A shell is fired at a 30-degree angle and remains airborne for 40 seconds, prompting calculations for its range and maximum height. To find the horizontal distance it lands from the original position, the projectile motion equations can be applied, specifically focusing on time of flight and initial velocity components. The highest point can be determined using the vertical motion equations, factoring in gravitational acceleration. Clarification is sought on whether the 40 seconds refers to time or velocity, indicating confusion about the problem's parameters. Understanding the correct application of projectile motion equations is essential for solving the problem accurately.

The Attempt at a Solution


I was unparticularly sure because the q says 40 seonds- should it be 40m/s

Is

v = v_{0} +gt

a familiar equation?
 
Use your linear motion equations.

v = u+gt
s = ut + 0.5gt^2
and v^2 = u^2+2gs

make an inventory of what parameter values you have and see which equation suits it best...
 
No not really. Just wondering how you solve this.
 
thank you.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
