A cannonball is fired from the ground level at an angle of 60 degrees with the ground at a speed of 72 m/s. How long does it take the cannonball to reach it maximum height? what is the cannonball's total time of flight? what is the cannonball's range?

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

overcharge is the right answer system

your answer is, orbit around the nucleus
