A 350 N uniform 1.50 m bar is suspended horizontally by two vertical cables at each end. Cable A can support a max tension of 500 N without breaking and cable B can support 400 N. You want to place a small weight on this bar. What is the heaviest weight you can put on without breaking either cable?

A) 450 N

B) 500 N

C) 550 N

D) 300 N

E) 350 N

Where should you put this weight from the left end of the bar?

A) 0.40 m

B) 0.61 m

C) 0.75 m

D) 0.84 m

E) 1.0 m

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
