Awall clock has a minute hand with a length of 0.55 m and an hour hand with a length of 0.26 m. take the center of the clock as the origin, and use a cartesian coordinate system with the positive x axis pointing to 3 o'clock and the positive y axis pointing to 12 o'clock. what is the magnitude of the acceleration of the tip of the minute hand of the clock?

The magnitude of the acceleration of the tip of the minute hand of the clock .

Explanation:

Given that,

Length of minute hand = 0.55 m

Length of hour hand = 0.26 m

The time taken by the minute hand to complete one revelation is

We need to calculate the angular frequency

Using formula of angular frequency

Put the value into the formula

We need to calculate the magnitude of the acceleration of the tip of the minute hand of the clock

Using formula of acceleration

Put the value into the formula

Hence, The magnitude of the acceleration of the tip of the minute hand of the clock .
