On level ground a shell is fired with an initial velocity of 41.0 m/sm/s at 61.0 ∘∘ above the horizontal and feels no appreciable air resistance. 1. Find the horizontal and vertical components of the shell's initial velocity. 2. How long does it take the shell to reach its highest point? 3. Find its maximum height above the ground.
