How might the threshold go this time?

1. 1090J
2. a=2m/s2 m=0.6kg T=4.8N
3. 10m/s a=0.4m/s2
4. 39N direction 22.6' AC from x direction
5. 0=30' coefficient=0.693
6. gain in KE=344000J driving force workdone= 1220000J
7. distance OA=216m a=-0.72m/s2 u=17.6m/s

it is 5N for the tension :)

and for number 7 it is no way 17.6 cuz for max speed was 6.4 sooo.. it is 3.2m/s :)
and for the ke u get the u=4.44 and v=15 :) so u put in the ke formula and tadaa :) :p el7amdella

u r making me sad bro :( cuz that kinetic energy question is easy but i did a simple mistake that would take marks off me..i had one velocty 4.44 and the other one 13.1 instead of 15 for using the acceleration 0.4 instead of 0.2 arghhh :(

think the last u was 25.2 m/s and not 17.6.

the overall ppr was easy accept for the kinetic energy which was really a tricky one.How was the paper worldwide? i believe the threshold would not be more than 38 for A.

the ques said initial speed at 0 so the max speed it said was attained at t s after journey while the ques asked for speed when t=0 when p is at O so it has no link with max speed

how did u get that speed then if t = 0 so the velocity should be equal to zero according to the equation given ?

no it was not 4.44 or either 15 i guess u qouted the accelerations as speed the ques had give initial and final accelerations not speeds
