Answer:
B. silicate rocks and metals
This is a trick question, isn't it? If a car is stuck in traffic, it doesn't matter how fast it can travel, because it isn't moving at all. Therefore the average speed would be zero, right?
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
