60 A centripetal-acceleration addict rides in uniform circular motion with period T = 2.0 s and radius r = 3.50 m. At t, his accel- eration is a = (6.00 m/s2)î + (-4.00 m/s²)j. At that instant, what are the values of (a) v.a and (b) 7 x a?

60 A centripetal-acceleration addict rides in uniform circular
motion with period T = 2.0 s and radius r = 3.50 m. At t his accel-
eration is á =
%3D
(6.00 m/s²)i + (-4.00 m/s²)j. At that instant, what
%3D
are the values of (a) v.a and (b) 7 × d?
