A charged ink droplet in a continuous inkjet printer is directed horizontally at 12 m s-1 into a deflection region where it experiences a constant vertical acceleration of 3.2 × 104 m s-2.
What is the horizontal distance travelled by the droplet in this region when its vertical displacement is 4.0 mm?
