nazli father buys a bar fridge with a mass of 30kg. he unloads the box containing the bar fridge in his driveway and starts to push it towards the house. at first he has to push with a force of 135N to get the box to start moving. once it is moving, he has to exert a Force of 120N to keep it moving with a constant speed. for the box on the driveway, calculate the maximum coefficient of static friction?​ calculate the coefficient of kinetic friction

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
