A)Find the speed of the particle.

Speed = ____________

(include units)

B)Find the first positive time when the particle comes to a stop.

t=_____

(include units)

C)If n is any odd integer, write a formula (in terms of n) for all positive times t at which the particle comes to a stop.

t=______

(include units)

For the first one I got sqrt((-2sin(2t))^2+(cost(t))^2) ft/s, which is wrong, and I dont know why....

I don't know ho to calculate the second and third part... please someone help...
