HELP PLEASE A 51.7 kg hiker that ascends a 43.2 m hill at a constant speed of 1.20 m/s. It takes the hiker 384 seconds to reach the top. On the journey the hikers potential energy is___
The total change in gravitational potential energy for the hiker is The amour if work done by the hiker to reach the top of the hill is___
The hiker requires watts of power to get to the top of the hill in 384 seconds

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 

The best answer i can think of is b

Hey did u get the answer?
