In a prototype helicopter, a jet is expelled out of the helicopter's side to make it turn in the opposite direction. If the jet supplies 10,000 N of force and the helicopter's forward speed remains at 20 m/s, what is the radius of the helicopter's turn?

    The radius is (0.04m) meters

    Explanation:

    F = mv^2/r

    m is the mass of the helicopter = m kg

    v is the speed of the helicopter = 20 m/s

    F is force supplied by the jet = 10,000 N

    10,000 = m*20^2/r

    r = 400m/10,000 = 0.04m

    The radius is (0.04m) meters
