Ok, I think I've got it...
a) 18.75m/s^2
b) 150 m
c) 6 seconds, 1425 m including the first 1200
Is this right? And thank you everyone, for all the help!
Oh, I'm sorry. I think I forgot that aspect of the problem... Yes, the car accelerates from rest. Also, I'm not sure how I should solve it even after reading azizlwl's comment..?
This question was on my practice exam last week. However, I had no idea how to solve it, since plugging the variables into formulas left me with TWO unknown variables (no matter what formula), making any of them impossible to solve.. But there must be a solution. I'd be very grateful if you...
