A projectile is shot on level ground with a horizontal velocity of 17 m/s and a vertical
velocity of 34 m/s.

-Find the time the projectile is in the air.
The acceleration due to gravity is 9.8 m/s2.
Answer in units of s.
-Find range R.
Answer in units of m.

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.

wavelength divides in half and speed stays the same.

im guessing the west of station b
