a giant crane was tested by lifting 2.232*10^6 kg load.find the magnitude of the force needed to lift the load with a net acceleration of 0m/s^2. if the same force is applied to pull the load up a smooth slope that makes 30 degrees with the horizontal, what would be the accel

if it is moving at constant velocity (zero acceleration), then the force is equal to its weight,mg

Now up a 30 degree slope, without friction.

netforceup=ma
mg-forcedownplane=ma
mg-mgSin30=ma
solve for a.
