This is probability and random processes for electrical and computer engineers

solve ONLY 4.36

A 300 g platform is launched at point A from an aircraft that is traveling at 5, 500 ft with a speed v_A of 345 Km/h and at an angle, Theta_A of 10 degree with the i-direction as shown in Figure 1. Assuming the problem to be two-dimensional and neglecting drag exerted on the platform, determine: (a) the maximum horizontal distance, d the platform will travel in the air before reaching the ground at point B; (b) the angle Theta_B, of its trajectory when it reaches the ground at point B; and (c) the force exerted on the ground at point B.

Explanation / Answer

here as given Y=2x

hence mean of Y =2*E(X)=2*2=4

and Variance of Y =22*var(X) =4*2=8

hence std deviationof Y =(8)1/2 =2.8284

please provide detail of second question as it is not clear
