Hey there, this should be a very simple problem, but again, I haven't had much guidance in finding formulas with differentiation. If anyone could help me with this i'd greatly appreciate it as it can help me to understand the others.
Characteristics of SHM are displacement (x) and time (t)...
Hey everyone. This has been really bugging me for 4 hours now, and I cannot figure out where I am going wrong. If anyone can help me that would be greatly appreciated.
The current flowing through a capacitor is:
I = Ioe^-(kt)
Io = 2 amps
k = 0.2s
T = time
Find the charge flowed...
Thanks for replying! :D
Well he's accelerating (doesnt say how much), so he's definitely pulling the whole box up including himself.
I just took into account that if he's pulling the cradle up then the floor is lifting him 650N, and the fact he's pulling the rope means a further 650 must...

The buillder has a mass of 75kg and the cradle has a mass of 35kg. The builder...
Thanks for your help! :D I am not sure if I am doing it right still though as when I do the first equation of sincos = acceleration/gravity I get 0.255, and when I do the second equation that you gave me I get weight ^2 = 614,656kg, net force ^2 = 40,0000 + normal force^2 = 40000. The answer I...
Hey everyone, I'm new here, and just wanted to say hi first. Second, I was wondering if anyone would so kind as to help me with this problem.
