5 The resultant of the force \(\binom { - 4 } { 8 } \mathrm {~N}\) and the force \(\mathbf { F }\) gives an object of mass 6 kg an acceleration of \(\binom { 2 } { 3 } \mathrm {~m} \mathrm {~s} ^ { - 2 }\).
- Calculate \(\mathbf { F }\).
- Calculate the angle between \(\mathbf { F }\) and the vector \(\binom { 0 } { 1 }\).
