SUMMARY
A baseball player sliding into third base at an initial speed of 7.90 m/s experiences a coefficient of kinetic friction of 0.41 with the ground. To determine the distance the player slides before coming to rest, the net force equation f(net) = ma is applied, where the frictional force is calculated as f(friction) = μ(k) * g * m. The acceleration is derived as a = μ(k) * g, and the distance can be calculated using the kinematic equation d = 1/2 * a * t^2 + v(initial) * t, with the understanding that gravitational acceleration g is negative.
