The 0.5-kg cylinder A is released from rest from the position shown and drops the distance h, It then collides with the 0.4-kg block B; the coeffi- cient of restitution is e = 0.8. Determine the maxi- downward displacement h2 of block B. Neglect all friction and assume that block B is ini- tially held in place by a hidden mechanism until the collision begins.

A small projectile is fired vertically downward into a fluid medium with an initial velocity of 60 m/s. Due to the drag resistance of the fluid, the projectile experiences a deceleration of a = (-0.4v³) m/s², where v is in m/s. Determine the projectile's velocity and position 4 seconds after it is fired.
