Topic: Acceleration Problems
Objective: I will practice multiple ways to solve word problems that involve acceleration.
Science starter: Is the
object speeding up or
slowing down? Draw a
Motion diagram.

2. PUT IN REFERENCE SECTION#1 A C E L R T I O N
a = Vf – Vi t #2
t = Vf-Vi a
Vf = Vi + at
Vi = Vf - at
PUT IN REFERENCE SECTION #3 #4

3. 1. A cart rolling down an incline for 5
1. A cart rolling down an incline for 5.0 seconds has an acceleration of 4.0 m/sec2. If the cart has a beginning speed of 2.0 m/sec, what is its final speed?
