Both start from rest, but experienced Stan leaves the starting line 1.00 s before Kathy. Assume Stan moves with a constant acceleration of 3.45 m/s2 and Kathy maintains an acceleration of 5.10 m/s2.

(a) Find the time it takes Kathy to overtake Stan.

(b) Find the distance she travels before she catches him.

(c) Find the speeds of both cars at the instant she overtakes him.

Kathy's speed =

Stan's speed=
