Acannonball of mass 28.7 kg is shot into the air at an angle of 45 degrees with respect to horizontal. at the top of its ballistic trajectory, the cannonball suddenly explodes into two separate pieces, a smaller piece this is 1/3 the original mass, and a larger piece that is 2/3 the original mass. the smaller piece ends up landing right back at the spot where the cannonball was originally launched, 16.3 seconds after it was launched. how far from the launch site does the larger piece travel? you can neglect the effects of air resistance

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
