A car accelerates uniformly from rest to a speed of 23.3 km/h in 5.5 s. how far did the car travel?

Answer 1

figure it out for yourself *** wizard

Answer 2

First, convert 23.3 km/h into m/s to avoid any problems, so it would be 6.47 m/s.

Next, find acceleration: a=6.47-0 / 5.5 = 1.18m/s²

Now that you have acceleration, you can use the formula for displacement:

d=v0*t+ 0.5*a*t²

t=time

v0= initial velocity

a=acceleration

so...

d=0*5.5 + 0.5(1.18)*(5.5)²

d=0.5*1.18+30.25

d=17.85 meters
