Two particles A and B of mass 4kg and 3kg respectively are connected by a light in extensible string which passes over a smooth fixed pulley. The particles are released from rest with the string taut.
a) Find the tension in the string
b) When A has traveled a distance of 2m it strikes the ground and immediately comes to rest
Assuming that B does not hit the pulley find the greatest height that B reaches above its initial position.
So i found the tension to part a which is 33.6N
This is what i did for part b):
I found the a=1.4ms^2
For A: u=0 s=2 a=1.4 v=?
V^2=u^2 +2as
I got 2.4m/s 2sf
For B:
u=2.4 a=1.4 v=0 s=?
V^2=u^2 +2as
I got 2.1m
Can anyone help me identify where i faulted please.
