A 3.0kg cannon ball is shot from a cannon at a speed of 20m/s. The cannon is oriented 50 degrees above the horizontal and the cannon’s barrel is 8.0m above the ground. You want to position a mat that will catch the cannon ball. a. Determine how much time the cannon ball will spend in flight.
. A 3.0kg cannon ball is shot from a cannon at a speed of 20m/s. The cannon is oriented
50 degrees above the horizontal and the cannon’s barrel is 8.0m above the ground. You
want to position a mat that will catch the cannon ball.
a. Determine how much time the cannon ball will spend in flight.
b. Draw a force diagram for three points during the cannon ball’s flight (1) while it
is being shot from the cannon, (2) when it is at its maximum height, and (3) when
it is half-way between the maximum height and the mat.
c. Determine the horizontal distance from the end of the barrel where you should
place the mat so that it will catch the ball.
d. How fast is the cannon ball moving just before it hits the mat?
