An object with a mass of 10 kg is moving along a horizontal surface. At a certain point it has a speed of 28 m/s. If the coefficient of friction between the object and the surface is 0.40, how far will the object go before it comes to a stop? Use g = 10 m/s².

We need to use the formula for distance traveled while decelerating: 
d = v^2 / 2μg 
where d is the distance, v is the initial velocity, μ is the coefficient of friction, and g is the acceleration due to gravity. Plugging in the given values, we get: 
d = (28^2) / (2*0.40*10) = 98 m 
Therefore, the object will travel 98 meters before coming to a stop.
