The fоrce F exerted оn а bаll during а cоllision with a wall is given as a function of time t by the equation F(t) = αt - βt2, where α = 800 N/s and β = 2000 N/s2. The ball first contacts the wall at t = 0, and the collision lasts for 0.10 s. What is the magnitude of the change in momentum of the ball?
