I got T1=10 and T2=30 .. and was getting speed 100 sumthing.. quite unbelievable.. but i double checked many times..... And for Q5 i somehow got the answers 112 m/s and 113 m/s for mand q resp... which is wrong i am sure.. And what was the magnitude of F in the forces question where alpha was 84 sumthing....
And the graph for Q7 had two stationary points.. it had a curvy N shape.. and v=5 m/s at t=o
