a 2,000. kg ore car, initially moving at 5.00 m/s, rolls down a 50.0 m frictionless incline having an angle of 10.0 degrees relative to the horizontal direction, and then rolls horizontally 10.0m. there is an horizontal spring at the end of the 10.0 displacement. if the spring constant of the spring is 355 kN/m, what distance will the car be stopped?

    a block of mass 10 kg is initially at rest when it slides down a frictionless incline whose height is 10 m and is pitched at an angle of 30 degrees. At the bottom of the incline the mass encounters a horizontal surface that has a coefficient of kinetic friction of 0.4 with the mass. How far from the bottom of the incline will the mass come to a stop?
