When a cannon fires a cannonball, the center of mass of the cannon-cannonball system:Select one:a.Moves in the opposite direction of the cannonballb.Moves first in the direction of the cannonball, then in the opposite directionc.Moves in the direction of the cannonballd.Remains stationary

After firing a cannon ball, the cannon moves in the opposite direction from the ball. This an example of:

A knight atop a high castle is preparing a canon to fire. The canon is aimed horizontally, and just as the canon fires, the knight clumsily knocks over a spare canonball off the wall and it falls vertically down to the ground. Assuming both canonballs leave the wall from the same height, which will hit the ground first? Both hit the ground at the same time. The canonball that falls vertically down. The canonball fired from the canon.

On flat ground, a cannonball is shot with a speed of v = 13.3 m/s over a wall ofheight h = 5 m located a distance d = 10 m away from the cannon. If xmax is the farthest away the ballcan be shot over the wall and xmin is the shortest distance the ball can reach while going over the wall,find xmax − xmin.

A 40-kg cannon ball is moving at a speed of 1.5 m/s. How much kinetic energy does the cannon ball have?

Answer all questions.A cannonball is launched horizontally with an initial velocity of 36 m s–1 from the edge of a cliff 200 m high. Assume that air resistance is negligible.(a) Calculate the total time that the cannonball is in the air.[2](b) Determine the horizontal distance from the bottom of the cliff to where the cannonball hits the ground.[2](c) The mass of the cannonball is then doubled. Assume launch speed is the same. Explain whether this will affect the answer in part (b).
