In a pickup game of dorm shuffleboard, students crazed by final exams use a broom to propel a calculus book to the right along the dorm hallway. If the 3.50 kg book is pushed from rest through a distance of 0.900 m by the horizontal 25.0 N force from the broom and then has a speed of 1.60 m/s, what is the coefficient of kinetic friction between the book and the floor?

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

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 answer is "iron"
