Answer:

The weight of the scaffold is 375 N.

Explanation:

It is given that,

The weight of the person in the middle, W = 225 N

Tn tension in each rope, T = 300 N

Let w is the weight of the scaffold. On equilibrium, the net forces can be written in terms of :

w + 225 = 300 + 300

w = 375 N    

So, the weight of the scaffold is 375 N. Hence, this is the required solution.

For some reasons, no. If the driver looks focused and has experience, then it would be okay. Again, it could be dangerous if you bump into the truck, it would cause damage to you and your passengers. 

Mostly, I would agree with 'No'. :)

What is newton's second law of motion?
lord [1]

Answer:

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
