Homework Statement
n my homework we are asked to find the magnitude of the reaction force at the pivot at a instant and earlier in the problem we found the magnitude of the angular speed at one instant, the magnitude of the angular acceleration at the same instant, and the magnitude of the acceleration of its center of mass at the same instant
PROBLEM # 13
Homework Equations
I am lost now.... am attaching the picture
The Attempt at a Solution
F= (4.5)(16.43509961) (my numbers)
but the answer is wrong..
than I tried
F= ma
F= (4.5)(7.350000002) (transitional acceleration only)
answer is still wrong :(
my numbers =
angular acceleration= 2.133526851
angular velocity= 2.065684802
Net acceleration= 16.43509961
mass 4.5
rod 6.89
What am I doing wrong?
