Question

a pully has a mass of 2kg one one side and 4kg on the other side.

calculate the acceleration of the system

The net force on each block

The tension in the string connecting the blocks

Answer 1

acceleration is g/3
2kg up and 4kg down

Answer 2

tension is 8g/3

Answer 3

net force on 2kg block is 2g/3 upwards and 4g/3 downwards on the 4kg block

Answer 4

please give exact value

Answer 5

assume gravity is 9.81

Answer 6

the heavier will drag the lighter, so T=4kg(g)-2kg(g), gis gravity, lets say it is 9.8m/s²
net force act on the heaver obj = 2N (downward force)


F = ma, where the mass of whole system is 6kg so:
2N=6kg(a)
a=1/3m/s² , acceleration

Answer 7
