## Homework Statement

Calculate the speed of the minute hand on the clock (I solved with the assumption of the minute hand being the radius) with the length of 25 cm.

How many degrees did the minute hand move through from 12" point to 2" point?

What is the average acceleration?

## Homework Equations

a=change in V/change in time

## The Attempt at a Solution

So i found the speed of the hand by finding circumference then divided over 3600 seconds.

Now I need to find the angle from 12" to 2". Is it right to assume that 2" is at 45 degrees, if 3" is 90 degrees?

Which method should I use the component or the trig method?

please help.

PS: is there a way to illustrate this and post it up?
