Example: A car starts from rest and uniformly accelerates to a final speed of 20.0m/s in a time of 15.0s. How far does the car travel during this time?

Sorry if this is complicated...

Answer: 150m

Step-by-step explanation:

4=0

v= 20.0m/s

T= 15.0s

__________

x=? x=VT t= 150m

_____

T X= UT = 9/2 T2= 150m
