Net force

  1. Nov 16, 2007 #1
    An aircraft carriers capapult accelerates a 2000-kg jet aircraft from rst to a lauch speed of 320m/s in 2.0s.

    a) The net force on the plane is ?
    b) the lenght of the catapult is ?

    F= m/a Lenght= at^2/2 vf=vo*at

    320m/s= (0) * a * 2.0s
    a= 160 m/s

    F= 2000kg * 160m/s
    = 320,000 N

    b at^2/2 160*4/2= 320M

    Is this right

    3. The attempt at a solution

    "F= m/a Lenght= at^2/2 vf=vo*at " ? NOT right.

    ok yeah, I meant to put the + sign instead of *.
