OBJECTIVE The objective objective of this of this r epor epor t is to pro provide vide a program program C to help the user ser dete determ rmine ine the displa displacem cement and accelera ccelerati tio on at cer cer t ain tim ti me per per iod based based from a given given data of ti of tim me and velo velocity of an an object object and also lso inclu includes the f low char char t of the of the p program. rogram.
ALGORITHM
