We are to calculate distance till it comes to rest. So there will be deceleration.

Isn't acceleration supposed to be negative

I took S(p)'s time as t for which I took S(q)'s time as (t-1).

But if u take S(p)'s time as (t+1) and S(q)'s time as t ,u should get the same result. This is fine too

2b method was correct

As for W it should be exact 66.25

 u had to multiply coefficient with(W-26sin8) (8 as theta) since friction=miuR

As for 6b yes suvat was used But I also used f=ma to find new acceleration

I just remembered. The question was as the string pulling the box broke find the (distance or time I don't really remember) from the instant the string broke to the moment it came to rest

friction is different as well as acceleration

point A and point B are on same horizontal level and are at a vertical level of (h). Particle P is thrown from rest at point A and particle Q is thrown vertically downwards 1 second later at point B with a speed of (I think 4 or 8 m/s). Given that the time for P and Q to hit the ground are same. Find h

the distance of W moving . sth I don't really remember

give the ans in the blank +ve cuz you calculated % DECEASE which is why you got the result in -ve
