a car traveling at 30 m/s loses a tire. the tire rolls to a hill which it begins climbing without slipping how high up the hill will the tire climb?

  • physics(i also hae no idea) -

    Kinetic energy at bottom = potential energy at top

  • physics(i also hae no idea) -

    (1/2) m v^2 + (1/2)I w^2 = m g h
    but w = v/r
    (1/2) m v^2 + (1/2)I v^2/r^2 = m g h
    v^2 (m + I/r^2) = 2 m g h

    You must know something about radius and moment of inertia to get answer.

    omg thank you i forgot about kinetic energy and potential energy
