with a velocity \( u=4.0 m / s \) from the top of a high tower. During the flight of the ball, modulus of the force of air resistance on the ball is given by equation \( F=h v \). here \( k=0.41 kg / s \) and \( v \) is the speed of the ball. The tower is so high that the ball achieves aconstant speed before striking the ground. Find velocity of the ball, when its kinetic energy changes most rapidly. Acceleration due to gravity is \( \bar{g}=10 m / s ^{2} \). \[ \begin{array}{l} K=\frac{1}{2} m \\ \frac{d K}{d t}=\frac{m}{2} \\ \left(W_{011}\right)=\frac{d}{d t} \end{array} \]

Three robots are tested for synchronization in remote communication and are kept in different places. The first one would beep or light with probabilities 2/3 and 1/3 respectively. The second one would receive and communicate the same to the third. The second and third robots would transmit with a precision of 80%. Let p be the probability that the third robot beeps, when the first one actually lighted. Then 31 p equals:
