This is the oldest version of book. Why taking this?International A/AS Level Physics
can someone post an online link for this book (pdf version or something)
thanks in advance
a : 4secPlz tell me how to solve this question
Q. A speeding motorist is travelling at a constant speed of 40 m/s on a motorway. He passes a stationary police car which immediately accelerates at a rate of 2.5 m/s^2 to a constant speed of 50 m/s. Draw a sketch graph showing the variation of speed against time for each car and find
a. The tine it takes for the police car to catch the motorist
b. The distance each will have travelled by that time
You've just cloned the marking scheme's answer. Why is the percentage uncertainty of R half the sum of the % uncertainties?
Now it much better. Thankscheck again
No the correct answers are 50s and 2000mThe Sarcastic Retar50 post: 879120 said:a : 4sec
b : Distance of motorist will be 238.4 Km and for police car : 278.4 Km
Are those answers correct?

Question 2 (a) ii)
Why do I get an incorrect answer when I use the formula?:
v^2 - u^2 = 2as
- (7.29)^2 = 2 (-9.81) (s)
Furthermore, the marking scheme doesn't mention this formula? Why can't I use it?
Its may june 2014 question paper 11why paper is this? i alreadt solved this. it's available @
http://physics-ref.blogspot.com/
search in the papers there
thanks that has help me a lot
