Use the rotational form of Newton's second law to determine the angular acceleration of the ladder.
The ladder has a mass of 5.0kg and is 4.0m long. angular position 1.0 radians above the horizontal surface. Assume that the ladder has a uniform mass distribution and that the gravitational constant is 10.0N/kg.
Determine the angular acceleration of the 5.0kg, 4.0m-long ladder when it is at the 0.80rad position.
