Find , the constant force with the least magnitude that must be applied to the board in order to pull the board out from under the the box (which will then fall off of the opposite end of the board).

It didn't specify in the problem.

Homework Statement A Federation starship ( 1.90×10^6 kg) uses its tractor beam to pull a shuttlecraft ( 2.00×10^4 kg) aboard from a distance of 11.0 km away. The tractor beam exerts a constant force of 4.0 x 10^4 N on the shuttlecraft. Both spacecraft are initially at rest. How far does...

Please help! Finding minimum force! Homework Statement A small box of mass m_1 is sitting on a board of mass m_2 and length L (Intro 1 figure) . The board rests on a frictionless horizontal surface. The coefficient of static friction between the board and the box is mu_s. The coefficient...
