How much power is required to push a box 4.0 m with a force of 150 n in 2.5s? a. 15w b. 1500w c. 240w d. 94w

Answer

the anser is (C) as 240 Watt

Explanation

As we know that

As given in question

Force = 150 N

Distance = 4m

Then work is

So the answer is 240 watt

The answer is frictional force

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
