Isn't velocity Distance over time? if the degree isn't adding resistance it should be 4000 ÷ 20 which gives you 200mps ("per second") which is the velocity without resistance.

Explanation:
Explanation:
Given
height of building (h)=54 m
Projectile velocity=330 m/s
initial vertical velocity
Initial horizontal velocity
Time taken to cover vertical height of 54 m
t=3.31 s
Horizontal distance traveled in this time
Vertical component of velocity when it hits the ground
v=u+at
Answer:
transparent Prism
Explanation:
The device shown is a prism. It is used to study the refraction of light according with its wavelength as it transverses from a medium (air for example) to another (either glass, fluorite, plastic), and vice versa.
For that reason is also used to separate white light into its spectral wavelength components.
