- 2.A train slows from 30 m/s to 10 m/s in 5 s. Find the acceleration.
- 3.A dropped ball speeds up from 0 m/s to 20 m/s in 2 s. Find the acceleration.
- 4.A car travels a circular track at a constant 20 m/s. Is it accelerating? Why or why not?
- 5.What does it mean if an object has an acceleration of 0 m/s^2?
