1. The problem statement, all variables and given/known data What is the initial force P required to accelerate the table upwards at 0.3ms^2. 2. Relevant equations I have attached the the problem, it is drawn out in paint. The mass expected to be carried on the table is 200kg and can be assumed to be a point mass acting at the position shown on the diagram. Assuming that the table moves vertically and does not rotate under the force P, I need to find what value it initially must be so that it causes an initial acceleration of 0.3ms^2 upwards. 3. The attempt at a solution I have tried for a day to work this out and I am not getting anywhere! any help would be very much appreciated.
