Kinematics Problem on hot air balloon

AI Thread Summary
The hot air balloon rises at a constant rate of 1.30 m/s, while a passenger's friend tosses a camera upward with an initial speed of 9.40 m/s from a point 2.30 m below her. To solve the problem, one must consider the distances traveled by both the balloon and the camera over the same time interval. The balloon's distance can be expressed as x, while the camera's distance is x + 2.30 m. By applying kinematic equations, the time it takes for the camera to reach the passenger and her height at that moment can be determined.

A hot air balloon has just lifted off and is rising at the constant rate of 1.30 m/s. Suddenly, one of the passengers realizes she has left her camera on the ground. A friend picks it up and tosses it straight upward with an initial speed of 9.40 m/s. If the passenger is 2.30 m above her friend when the camera is tossed, how much time does it take for the camera to reach her? How high is the passenger when the camera reaches her?

I am not completely sure how to even start this. I know you have to factor in that the air balloon is rising as she is throwing the camera in the air, but i do not know how to factor that inforation in. Help would be greatly appreciated. Thanks

Hot air balloon is moving with constant acceleration. Camera is tossed with some initial velocity. When the passenger catches the camera, the distance traveled by her is x and the distance traveled by camera is x + 2.3 m. These distances were traveled in the same time interval. Using kinematic equations, find t and x.
 
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...
