Boom!
A great bombard launches a projectile in a high arc, with an initial velocity of 49.0 m/s vertical component upwards and 15.3 m/s horizontal component due east.
How far east of the great bombard will the projectile land, assuming the battlefield is flat? Give answer in meters.
The answer is 153.

The acceleration of gravity is 9 . 8 m / s 2 vertically downward.
So the great bombard's projectile will take (49.0/9.8) = 5 seconds to reach peak height and an additional 5 seconds to come back to earth. It is therefore in the air for 10 seconds. The horizontal component is constant, so at 15.3 m/s, multiplying by 10 yields 153 m horizontal travel.
