Homework Statement
A 7kg mass is hung from a 1.5 m long massless string. It is released from rest with the string displaced by
an angle of 18 degrees from vertical.
a) Make a free body diagram of the forces on the mass just after it is released.
b) Find the tension in the string.
c) Find the initial acceleration of the mass.
Homework Equations
F = ma
The Attempt at a Solution
b) Fy: Tcos18 - 68.6 = ma
Does ay = 0? And if it does then why exactly? Is it just cause they want the tension at that point so the object is not assumed to be moving?
However there will be an ax value right?
Thanks.
