How do you do this question below? :
Calculate the angular displacement in radians of the tip of the minute hand of a clock in one second.
Thanks!

But you don't know the angular speed!

I don't know, had my first A2 lesson today, so haven't got that far :/

To get angular velocity,W = 2pi/t =]

T= 1/60seconds if I am not wrong.Make sure your calculator is in radians ,the value which you get,plug it into the above formula,cha ching.

First find angular velocity which is 2pi/ T,
T= 1/60seconds if I am not wrong.Make sure your calculator is in radians ,the value which you get,plug it into the above formula,cha ching.

I would:
1) Find out how many degrees a clock goes round in 1 second (360/60)
2) Convert this to radians. (radians = degrees * (pi/180))
Although I may not be right. Do you have any access to the answer?

Because it is the minute hand, you do
60 x 60 = 3600
so that is 1/3600 x 2pi
= 1/1800 pi
60 x 60 = 3600
so that is 1/3600 x 2pi
= 1/1800 pi

First: you have to calculate the degrees of the arc length. 360/60 = 6 degrees
Second: you must convert the degrees into radians. (2pi/360) * 6 = 0.1047... radians
Third: radians * time = 0.1407 * (1/60) = 1.75 * 10^-3 rad s^-1
