Estimate the magnitude of the force, in Ibf, exerted on a 20-lb goose in a collision of duration 2 x 10 3 s with an airplane taking off at 150 miles/h. Assume the bird's velocity is zero before the collision. Estimate the average acceleration magnitude, in ft/s2, of the goose in the collision. Estimate the magnitude of the force, in Ibf, exerted on the goose in the collision.
