City b is northwest of city a and the 400 mile trip by car takes 8 hours. city b is exactly 320 miles nw of city a if able to travel in a straight line. what is the velocity of the car?

0 mph n
40 mph nw
50 mph nw
80 mph ne

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

v 154.9= 0.9 length length s little over 154.9cm

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
