. On level ground a shell is fired with an initial velocity of
at 60.0° above the horizontal and feels no appreciable air
resistance. (a) Find the horizontal and vertical components of the
shell’s initial velocity. (b) How long does it take the shell to reach
its highest point? (c) Find its maximum height above the ground.
DHow far from its firing point does the shell land? (e) At its
highest point, find the horizontal and vertical components of its
acceleration and velocity.
