1. The problem statement, all variables and given/known data A trailer with a mass of 900 kg with mass centre (centroid) at G is attached to a towing car at A. If the car and trailer reach a velocity of 60 km/h along a horizontal road in a distance of 30 m from rest with constant acceleration, compute the vertical component of the force at A. Assume the wheels are relatively light and that the friction force between wheels and road can be neglected. (Picture attached) 2. Relevant equations SUVAT Equations v^2=U^2+2as 3. The attempt at a solution I am not sure where to even begin with this question. I worked out the acceleration to be 4.6m/s but have no idea were to go or how to finish. If someone could help it would be much appreciated.
