While sitting on the Oval, you observe a squirrel running due east at vi = 0.70 m/s. The squirrel undergoes an acceleration of a = 1.4 m/s2at = 15north of east for t = 0.90 s in order to catch a falling nut. At the end of this motion, what is the angle between the squirrel's final velocity vector vf and its original direction of motion? For the representation, draw a tip-to-tail vector addition diagram relating together vi, vf , and v. For the limits check, investigate what happens to as the acceleration becomes extremely brief (t 0).

1) representation

2) physics concepts

3) initial equation

4) algebra work (symbols only. don't plug in any numbers yet)

5) symbolic answer

6) unit check

7) limit check

• a) as t-->0, what limit does theta approach?
• b) why does the result make physical sense?

8) numerical answer (obtain this by plugging numbers into your symbolic answer.)
