1. Recall Newton's 3rd Law of motion.

2. Recall Newton's 2nd Law of motion.
a) What does constant velocity involve?
b) Use F = ma
c) Use again F = ma

3. Same as 2.

4. Find the deceleration and then use F = ma.

5. Use

6.
a) Use to get the minimum force required to start the block and determine whether the force used is enough or not.
b) Use your answer to a)
c) Use then

7. Use

TRIAL 1

A. )
Bag A + 6 stones
Mass (kg) - 0.037 kg
Mass of weight hanger + slotted weights - 190 g/ 0.19kg
Tension 1 (N) -?
Acceleration (m/s2) -?

B. )
Bag B + 4 stones
Mass (kg) - 0.08
Mass of weight hanger + slotted weights - 190 g/ 0.19kg
Tension 1 (N) -?
Acceleration (m/s2) -?
Tension 2 (N) -?

C. )
Bag C + 2 stones
Mass (kg) - 0.074
Mass of weight hanger + slotted weights - 190 g/ 0.19kg
Tension 1 (N) -?
Acceleration (m/s2) -?
Tension 2 (N) -?
Tension 3 (N) -?

======================

FORMULAS

F=ma
T1 - Tabc = (Mabc)a
T2= ?
T3= ?
T2- Fbc = (Mbc)a
T3 - Fc = (Mc)a

=====================

Can you please write it in details, like how you get to the result and stuff because I still need to do trial 2 and 3
Thank you!

=====================

do you think that bag a,b and c with stones with a weight of 0.19kg would move if I placed slotted weights of 0.17kg or 19kg??

If there is a mass of 0.19 kg on the left side of the pulley. What is the mass needed on the other side of the pulley for it to move? 0.17kg, 0.19kg or something else?

I don't understand what you're talking about here... this is a trial for what question? :(

It will all depend on the pulley, but assuming a frictionless pulley, anything other than 0.19 kg will make it move.
