AI Thread Summary
An object is thrown upwards from a tower with an initial velocity of 29.4 m/s, while another object is dropped from the same height four seconds later. To determine when both objects are at the same level, one must use kinematic equations to express their positions as functions of time. Setting these position functions equal allows for solving the time at which they meet. The discussion emphasizes the importance of applying basic kinematic principles to solve the problem effectively. Understanding these concepts is crucial for accurately determining the time of intersection.

An object is thrown vertically up from the top of a tower with an initial velocity of 29.4m/s. Four seconds later another object is drop from the top of the tower. How many seconds will the two be at the same level?



I'm trying to solve it for a day already. Sorry, I suck at this :P

Well, try coming up with functions for position in terms of time using our basic laws of kinematics. Then set the two equal and solve.
 

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 '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...
