Ahistorical society is testing an old cannon. they
place the cannon in an open, level field and perform
a few test fires to determine the speed at which the
cannonballs leave the cannon. the cannon is placed
at a 45.0Β° angle from the horizontal and placed in a
bunker so that the cannonballs are fired from ground
level. they measure the flight time of one cannonball
to be 3.78 s. (2.3) m
(a) what is the speed of the cannonball as it leaves
the cannon?
