[طبيبة صآبره]

السلام عليكم ورحمة الله وبركااته ..

كيفكم ان شاءالله طيبين ,,
انا عندي كم تمرين بالفيزياء الطبيه أبي حلهااا قبل يوم السبت بليز وحكوون شاكره لكم ,, الدكتور اعطانا التمارين وقال حلوها وراح اعمل لكم كويز فيها يوم السبت لذلك ابي حلها سريعاً لا هنتوا ,,

====> إليكم التمارين من كتاب "kane and sternheim physics .third edition. "

1- (1-50) من الشابتر الأول:
A racing initially at rest has a conatant acceleration for 0.5 Km
its speed at the end of this period is 100 m/s
a\ What is the acceleration of the car
B\ How long does it require to cover the 0.5 Km distance



من الشابتر الثاني :
يوجد رسمة للسؤال سأحاول وضعها لاحقاَ

2.13
For the vectors in fig.2.22 find the magnitude and direction of
A\ D=A+B+C
B\ E=A-B-C

2.15

A car goes around a circular track 500 m in diameter at a constant speed of 20 m/s
A\ How long does it take for the car to go halfway around the track
B\ What is its average velocity in that time interval


2.19
A plane flies south at 500 Km/h for 2h and then flies west at 500 Km/h west for 1h
A\ What is its average speed
B\ What are the magnitude and direction of its average velocity


من شابتر الثالث :

3.49


An elevator cable that is light in weight compared to the elevator car can support a weight of 10.000 N . If the elevator and occupants
weight 8000 N , What is the maximum possible vertical acceleration of the elevator



3.54


In a collision , an automobile of mass 1000 Kg stops with constant acceleration in 2m from an initial speed of 20 m\s
A\ What is the acceleration of car
B\ What is the net forceon the car during the collision






وبليــز أبي حلها قبل يووم السبت والله يعين ويوفق الجميع
