Berdasarkan Hukum II Newton, maka percepatan yang dialami benda :

straight F space equals space 100 space straight N  straight m space equals space 10 space kg  straight mu subscript straight k space equals space 0 comma 3  sin space straight theta space equals space sin space 37 degree space equals space 3 over 5

 

Berdasarkan Hukum II Newton, maka percepatan yang dialami benda  :
