Acar starts from rest and accelerates at a constant rate of 4.5 m/s^2. what is the final velocity after traveling 1.6 km?

First write down all the known values:

vi = 0m/s

a = 4.5m/s^2

d = 1.6km = 1600m  Remember to convert to meters since the acceleration is in meters

vf = ?

Now use the kinematic equation that relates all these variables:

vf^2 = vi^2 + 2ad

vf^2 = (0)^2 + 2(4.5)(1600)

vf^2 = 14400

vf = 120m/s

The final velocity of the car is 120m/s.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
