A force of `(3 hat(i) - 1.5 hat(j)) N` acts on 5 kg body. The body is at a position of `(2 hat(i) - 3 hat(j)) m` and is travelling at `ms^(-1)`. The focce acts on the body until it is at the position `(hat(i) + 5 hat(j)) m`. Assuming no other force does work on the body, the final speed of the body.
