أعزائي المشرفين .. هل لي ان اطلب منكم خدمة....
وهي مساعدتي قي حل السؤالين التاليين ....
==============
a car traveling with an initial velocity of 100 km/hr experiences a negative acceleration of 1.50 m/s/s wen it applies the brekes. How many seconds does it take to stop? (hint: There are actually three given varibles, altough you may only see two. The word "stop" should be a hint to the third) how many meters does it travel before stopping?
----------------------------------
An iceboat experiences a gust of wind. It accelerates at a constant rate while it increases is velocity from 10 m/s to 30/s. during this time of accelearation, it travels 200m. What interim variable do you need to find before solving the problem? Find the rate of acceleration of the iceboat.
===================
ارجو ممن لديه القدرة على ذلك الا يقصر معي ... فأنا تخصص كيمياء وليس فيزياء
وشكرا
