The Cannon was set by mistake at 30 degree instead of 20 degree with the horizontal and was fired to hit the enemy targets. The Cannon shell will now fall at

Answer 1

Answer:

Canon will fall farther than target  

Explanation:

The Cannon was set by mistake at 30 degree instead of 20 degree with the horizontal

Canon Required at 20 deg

Let say velcoity = V

Vertical Velocity = Vsin20

Time to Reach top = VSin20/g

Time of Flight = 2VSin20/g

Horizontal Velocity = VCos20

Horizontal Distance = VCos20 *  2VSin20/g

= V²Sin40/g

Now It will go at 30 deg

= V²Sin60/g

Sin 60 > Sin40

Canon will fall farther than target
