1. Homework Statement
A 10 kg block is subjected to two forces (10i + 20j) N and (6i - 8j) N. The magnitude of the resultant acceleration is
(a) 2 (b) 3 (c) 4 (c) 5
2. Homework Equations
F=ma
3. The Attempt at a Solution
I was thinking maybe I should add the horizontal components to get the force acting horizontally, and then substitute that and the mass into F=ma to get 'a', but that way I get 1.6 m/s^2 which isn't even an option. Someone help, please?
