The jensens dccided to spend their family vaeation white water rafting. during one segment of their trip down the river, the raft (total mass = 544 kg) has an initial speed of 6.75 m/s. the raft then drops a vertical distance of 14.0 m, ending with a final speed of 15.2 m/s. how much work was done on the raft by nonconservative forces?

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
