A body of mass 2kg is in equilibrium under the action of three coplanar forces, P, Q and R where P=3xi-2yj N, Q=2yi-4xj N, and R=-11i+4j N.
a) Calculate the values of x and y.
The force P ceases to act. Find.
b) The resulting acceleration of the body in component form.
c) The magnitude of the acceleration, giving your answer to 1 decimal place.
i and j are unit vectors.
I am completely confused by this question, can anyone offer up a method?
Thanks!
