To calculate the impulse and the average force acting on the ball, we need to use the following formulas:

1. Impulse (J):
   Impulse is the change in momentum of the ball, which can be calculated using the formula:

   J=Δp=m(vf−vi)J = \Delta p = m(v_f - v_i)

   where:

   • mm is the mass of the ball,
   • vfv_f is the final velocity,
   • viv_i is the initial velocity.

   The initial velocity is towards the east (along the positive x-axis), and _______ ________ ________ ______ ____.
