Pulley System
Two unequal weights, A = 6KG and B = 4KG
What is the kinetic energy of the movement after 4 seconds?
I think my calculations are so far correct... please point me in the right direction.
Homework Equations
KE = 1/2mv^2
The Attempt at a Solution
Acceleration of the two weights
a = g (A-B)
-------
(A+B)
a = 10 (6-4)
---------
(6+4)
a = 2ms
Force of gravity acting on weights
Weight 'A' (6KG)
F = MA
F = 6 * 10
Weight 'B' (4KG)
F = MA
F = 4 * 10
Ive also made an attempt to calculate velocity:
Velocity of masses
V = Sqr 2gh (6-4)
------
(6+4)
= (Sqr Rt)100
= 10However I made another calculation and found the acceleration of the both weights to be 7.3, and by using SUVAT that the velocity is 29.3 with that figure of 7.3 for acceleration. To be honest I am completely lost, please help.
