What is the initial force P required to accelerate the table upwards at 0.3ms^2.
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.
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.
