Homework Statement
Particle A and B are attached by an inextensible string with masses 0.5 and 0.4 respectively
10N
^
|
{a}
|
|
{b}
take a to be 9.8 downwards
When the 10N is applied the particles move upwards. Ginf the tension in the lower string and the acceleration of the system.
Homework Equations
Kinematic Ones
Ignore air resistance
The Attempt at a Solution
A:
10 - T = 0.5a
B:T + 10 = 0.4a
BUT i think straight away this is wrong as what about the efffect of gravity?
Thanks
