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

Answer 1

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.

Answer 2

6 or 12
