An object passes the 120m position traveling with a constant velocity of -7.0 m/s a) where will it be after 10 secs have elapsed
b)how far does it go, if I'm 10 seconds it starts to accelerate at a rate of plus 2.0 m/squared and travels for 5.0 seconds more

(I have the answers but I'm not sure how my teacher got to them)
