AI Thread Summary
To determine the launch angle and speed of a hobby rocket that reaches a height of 72.3 m and lands 111 m away, the projectile motion equations can be applied. The launch angle can be calculated using the relationship between maximum height and range, while the launch speed can be derived from these parameters. The discussion emphasizes the importance of showing previous attempts to solve the problem for better assistance. The community encourages sharing specific calculations or methods tried to facilitate effective guidance. Understanding these principles is crucial for accurately solving projectile motion problems in hobby rocketry.

Ina projectile motion, if we measure the maximum
height h and horizontal range R
(1) How to get launch angle θin terms of h and R
(2) A hobby rocket reaches a height of 72.3 m and lands 111 m from the launch point.
What is the angle of launch?
What is the launch speed?


I already did part 1. Can you provide me help with part 2. Thanks

Hi gamacmua! Welcome to PF! :smile:

Show us what you've tried, and where you're stuck, and then we'll know how to help. :smile:
 

Thread 'Errors and significant figures'

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'

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'

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...
