A ball is thrown horizontally from a 20-m-high building with a speed of 5.0m/s a. make a sketch of the ball's trajectory.
b. Draw a graph of Vy, the horizontally velocity, as the a function of time. include units on both axes
c. Draw a graph of Vy, the vertical velocity, as the a function of time. include units on both axes
d. How far form the base of the building does the ball hit the ground

i am single too don't feel bad

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures

find the sum of the two horizontal vectors and the sum of the two vertical vectors
