My answers
1. Coefficient of friction. Its too small?? 0.0056
2. Kinematics
Distance is 0.5
Force is 0.016
3. Circular motion with bowl
I got the show that.
Using Theta and 2 theta. Circle theory rule
4. Hookes Law
Instantaneous change in acceleration is 3.92
2 × friction ÷ mass
5. Vertical circle
52 : 49
6. Simple harmonic motion
omega is root 250
Amplitute is root 10 / 10
Time is 0.293
7. Centre of mass
0.54 final ans

How did you do the instantaneous change in acceleration question?
by considering the directions of frictional force before reaching instantaneous rest and after reaching instantaneous rest the resultant forces are different and then calculate the change in acceleration
