so i found

v(t) = 4sint-t

a(t)=4cost-1 = 0 solved for t plugged it into v(t) and i got the wrong answer i got 3.2 something but the choices are

-5.19

.74

1.32

2.55

8.13

please help thank you

**Reiny**, Tuesday, March 30, 2010 at 8:16amDid you have your calculator set to radians ?

I get

t = arcsin(1/4)

= 1.318116

then

v(1.318116) = 4sin(1.318116) - 1.318116

= 2.55486

close to one of the choices,

(they should have rounded to 2.56)
