How do i get the displacement?

**Damon**, Monday, February 18, 2013 at 12:40amI already did this.

distance = 19*4 = 76 meters

v = Vi + a t

v = 25 - 3 t

v = 25 - 3(4)

v = 13 m/s after 4 sec

average speed during the 4 s = (25+13)/2 = 19 m/s

so distance = 19*4 = 76 meters

0 = 25 - 3 t

t = 8 1/3 seconds
