A 45-g bullet is fired with a velocity of 400 m/s at θ = 5° into a 9-kg square panel

 

A 45-g bullet is fired with a velocity of 400 m/s at θ = 5° into a 9-kg square panel of side b = 200 mm. Knowing that h = 150 mm and that the panel is initially at rest, determine (a) the required distance h if the horizontal component of the impulsive reaction at A is to be zero, (b) the corresponding velocity of the center of the panel immediately after the bullet becomes embedded.
