Homework Statement
A box of mass 20.00kg placed on a frictionless surface is pulled by two horizontal forces in the plane of the floor, as shown below. Determine the following quantities.
a) acceleration vector.
b) magnitude of resultant acceleration and its angle with the x-axis.
Homework Equations
f=m*a
The Attempt at a Solution
a) (F1-F2)/M=A
f1= 100cos(60)
f2= 200sin(30)
(100cos(60)-200sin(30))/20*9.8=a
a=-25/98
b) I am not sure how to do this.
