4. You are walking at a leisurely pace of .75 m/s when you hear the train coming and start running to catch it. Over the next 10 seconds, you speed up to 3.5 m/s and catch your train! What was your acceleration over that time?

Suppose the acceleration of the particle moving gin a circle of radius “r” with the uniform speed “v” is proportional to some power of “r , say and some power of “v” say “”.

Determine the powers of “r” and “v”.

Explanation:

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
