2. (a) The speed parameter β is v/c .Thu s , β = (3 cm / y)(0 . 01 m / cm)(1 y / 3 . 15 × 10 7 s) 3 . 0 × 10 8 m / s =3 × 10 18 . (b) For the highway speed limit, we fnd β = (90 km / h)(1000 m / km)(1 h / 3600 s) 3 . 0 × 10 8 m / s =8 . 3 × 10 8 . (c) Mach 2 . 5 corresponds to β = (1200 km / h)(1000 m / km)(1 h / 3600 s) 3 . 0 × 10 8 m / s =1 . 1 × 10 6
