    Solve Hot-Wheels Car Mass, Velocity for Height

    Homework Statement "A hot-wheels car of mass 0.0250 kg is traveling on a horizontal track with a velocity of 5.00m/s. If the track suddenly turns upward, how high up the track can the car travel?" Homework Equations work = mgh = force * distance PEf + KEf = PEi + KEi KE = .5mv^2...

    Finding the speed of a metal ball

    ok so then i would change my equation to KEf = PEi + KEi, and then from there use the equation KEf = .5mv^2 to solve for the velocity (speed), right?

    Finding the speed of a metal ball

    alright, so here's my question that i have to answer: "A ball of mass .500kg is rolling across a table top with a speed of 5.00 m/s. When the ball reaches the edge of the table, it rolls down a frictionless incline onto the floor 1.00 meter below (without bouncing). What is the speed of the...
