Webimpulse delivered to the ball by the ﬂoor. (b)Estimate the time the ball is in contact with the ﬂoor and use this estimate to calculate the aver-age force the ﬂoor exerts on the ball. Solution: (a) Impulse = D~p (1) = m(v~ f ~v i) (2) First we have to ﬁnd the velocity of the rubber ball before it hits the ground. WebThe impact occurs from t=0 to t=3.0 ms, and over this interval your force data is well fit by the function Fx (t)=at−bt^2 , where a=5.4*10^6 N/s and b=1.8×10^9 N/s^2. From this determine the total horizontal impulse delivered to the ball and the horizontal speed of the ball after the impact ends.
