[Haleemos]

A car travels from medina to makkah, a distance of 420 km. It covers the first 150km in 1h, stops for 0.5h , and covers the remaining distance in 2h.
~~~~~~~~~~~~~~~~~~~~~~
a) what is the magnitude of the displacment between Makkah and medinah?
~~~~~~~~~~~~~~~~~~~~~~
b) Draw the displacment vector (with south pointing toward the bottom of the paper) . Assume thet makkah is 15* east of south of medinah, and use a scale of 1cm = 100km.
~~~~~~~~~~~~~~~~~~~~~~
c) Calculate the car's average speed (v1) over the first segment of the trip.
~~~~~~~~~~~~~~~~~~~~~~
d) Calculate the car's average speed (v2) over the second segment of the trip.
~~~~~~~~~~~~~~~~~~~~~~
e) Calculate the car's average speed (v full) over the full trip.
~~~~~~~~~~~~~~~~~~~~~~
f) Draw three vectors representing the car's average velocity over the first segment, the second segment, and the whole trip. Use a scale of 1cm = 25km/h.
~~~~~~~~~~~~~~~~~~~~~~
g) Covert the three average speed (v1, v2, vfull) to m/s.
~~~~~~~~~~~~~~~~~~~~~~

ترجمة السؤال
بحسب فهمي[للفائدة] :
سيارة تسافر من المدينة إلى مكة تقطع 420 كيلومتر وتغطي في الساعة الواحدة 150 كيلو متر
خلال بداية الرحلة
وتتوقف لمدة نصف ساعة وتكمل المتبقي من المسافة في ساعتين ...

~~~~~~~~~~~~~~~~~~~~~~ a) what is the magnitude of the displacment between Makkah and medinah?

ماهي المسافة المقطوعة بين مكة والمدينة ...!
IF my transolate for Que Right I think
450 km
because the space which car distance
in Que is420km

~~~~~~~~~~~~~~~~~~~~~~ b) Draw the displacment vector (with south pointing toward the bottom of the paper) . Assume thet makkah is 15* east of south of medinah, and use a scale of 1cm = 100km.

this Que need to drawing
you can draw by the discribing of Que...!

~~~~~~~~~~~~~~~~~~~~~~ c) Calculate the car's average speed (v1) over the first segment of the trip.

حساب السرعة المتوسطة للمرحلة الأولى خلال الرحلة ...
v=x/t
v=150/1
so:v=150km/h

~~~~~~~~~~~~~~~~~~~~~~ d) Calculate the car's average speed (v2) over the second segment of the trip.

حساب السرعة المتوسطة خلال المرحلة الثانية من الرحلة ..
v=x/t
v=420-150/2
v=270/2
so:v=135 km/h

~~~~~~~~~~~~~~~~~~~~~~ e) Calculate the car's average speed (v full) over the full trip.

حساب السرعة المتوسطة ككل ...!
v=x/t
v=420/3.5
v=120km/h

~~~~~~~~~~~~~~~~~~~~~~ f) Draw three vectors representing the car's average velocity over the first segment, the second segment, and the whole trip. Use a scale of 1cm = 25km/h. ~~~~~~~~~~~~~~~~~~~~~~

this Que also you need to draw
you can draw it from the needed on Que

note: the answer in English Please I needed today Thank you very much [/COLOR][/SIZE][/FONT][/B][/LEFT]

p.s:
I’m not sure from all Que my brother
but this my try to help you
best wishes
for you
