GIVEN:
a(acceleration) -> 6.1 m/s^2
time-> 7 seconds
initial velocity-> 0 (since the car accelerates from REST)
D(displacement or distance travel)-> UNKNOWN

Formula: D = Initial Velocity (t) + 1/2 at^2
D= 0(7) + 1/2 (6.1 m/s^2) (7 s.)^2
D= 149.45 m
0
why is there a 1/2?
1/2 is a fixed number. It's originally in the formula.. :)))
slr, can you show me how the formula was derived? :)
