1hey u people are not answering my doubt...this is not done yet...plz complete it!
1n is this a pay site or a free site??will i get some added expense in my internet bill for using it??
66See figure:
The direction of the tangential and normal unit vectors are as shown. Its easy to see that
an = g cos θ and at = -g sin θ
Can you find θ as a function of time?
