two boxes, connected together one is 65kg the other 35kg, a force pulling on the 35kg box of 250N at 40degrees in a frictionless enviro, what is the acceleration and what is the tension between the 2 boxes

since the force is at 40 degrees, the horizontal component if the force is cos(40) * 250N
note that the vertical component of the force is insufficient to lift the 35kg mass since that would require 35*9.8N
and the force is sin(40)*250
the total mass is 100 kg
so a = cos(40) * 250/100
the tension between the boxes is the force on the 65kg box:
65*cos(40) * 250/100

If the perspective of the slope is small and expressed in radian you are able to basic multiply it with the gravitational tension to get the downward fraction of the gravitational tension. occasion. the perspective is a million%, the stress on 10 kg is mg = 9.8*10 = ninety 8 N. The downward tension alongside the slope is a million% * ninety 8 N = 0.ninety 8 N.
