Question

A cannon fires a 0.652 kg shell with initial
velocity vi = 12 m/s in the direction  = 61 ◦
above the horizontal.
The shell’s trajectory curves downward be-
cause of gravity, so at the time t = 0.473 s
the shell is below the straight line by some
vertical distance
h.
Find this distance
h in the absence of
air resistance. The acceleration of gravity is
9.8 m/s2 .
Answer in units of m
