hey
srry for being late but i was extremely busy with my exams

btw how was ur paper 1 ???
:)


man again i was busy with my exams
if u have any doubts in mechanics or P3 or P6 just inbox me :)
btw how was ur exam P1 ??
:)

A particle P moves in a straight line. It starts from rest at a point O and moves towards a point A on
the line. During the first 8 seconds P’s speed increases to 8 m s−1 with constant acceleration. During
the next 12 seconds P’s speed decreases to 2 m s−1 with constant deceleration. P then moves with
constant acceleration for 6 seconds, reachingA with speed 6.5 m s−1
.
(i) Sketch the velocity-time graph forP’s motion. [2]
The displacement of P from O, at time tseconds after P leaves O, iss metres.
(ii) Shade the region of the velocity-time graph representing sfor a value oft where 20 ≤ t ≤ 26.
[1]
(iii) Show that, for 20 ≤ t ≤ 26,
s = 0.375t
2 −13t +202.

q3??
i cant e ven resolve the forces..:(
PM me if u can!!

The tention in p1X and p1A will be the same, and the tention s in p2X and p2C will be the same, but they'll brcdifferentvfton each other. Find P1X and then calculate P1(X)B -angle X in that triangle. Next find P2(X)B by subtracting that angle from 90. Now you will have two known forces abd 3 known angles and so you can apply lamis rule to find the third force
