1) Car is uniformely accelerated at 0.7m/sec^2 from rest, for 60sec, travels at constant velocity for 5 mins and comes to rest after uniformaly retarding for 20sec
- total distance traveled?
*break it up into 3 parts: t in seconds
1. 0<t<60 <- x=.5*a*t^2, t=60
2. 60<t<360 <- velocity constant => x=vt
3. 360<t<420 <- x=360v-0.5*a*3600
add em all up .. figuring out why i chose what i did along the way (kinematic equations are simple enough that I leave comprehension to you)
that should get you started
any ideas much apreciated!
