Understanding Projectile Motion: Calculating Time and Velocity

AI Thread Summary
The horizontal velocity of the projectile is 33.97 m/s, which is used to calculate the time to travel from point C to G, rather than the initial velocity of 42 m/s. The initial velocity only applies at the start and end of the motion, while the horizontal velocity remains constant throughout the journey. The vertical velocity changes due to acceleration and deceleration, affecting the overall motion. The calculation for time is confirmed as 170/34, resulting in 5 seconds. This understanding of projectile motion highlights the distinction between constant horizontal velocity and variable vertical velocity.

it should say "show that the" NOT "sow that the"

The horizontal velocity is 33.97 m/s. (34 m/s)
Why do I use this value to calculate time to travel from C to G and not the initial 42 m/s.
Is it because the 33.97 m/s value is constant throughout the entire journey of the ball, BUT the 42 m/s value is only true for my initial and final velocity. In between, however, the value 42 m/s is different. This is true because the combined horizontal velocity and vertical velocity will change as the vertical velocity is affected by acceleration / deceleration (and time)

The correct calculation is: 170/34 = 5

Am i correct?

Yes, you are correct.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
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 hanging 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...
