Emma is pulling Ismay on a sled with a constant force of 90.0N at an angle 30 degrees of with the vertical. Ismay and the sled have a total mass of 60.0kg and they are moving across level frictionless snow.

Emma knows that Ismay will throw up once she reaches the exact speed of 10.0m/s. After what displacement should Emma stop pulling (at the constant force) so Ismay does not get sick?
