Two masses are joined by a massless string. a 30-n force applied vertically to the upper mass gives the system a constant upward acceleration of 3.2 m/ s 2 . if the string tension is 18 n, what are the two masses?

The mass of both masses are 0.923 kg and 1.38 kg.

Explanation:

Given that,

Upward force = 30 N

Acceleration = 3.2 m/s²

Tension in string= 18 N

We need to calculate the mass of first mass

Using balance equation

Where, m = mass

F = force

T = tension

a = acceleration

Put the value into the formula

We need to calculate the mass of second mass

Using balance equation

Put the value into the formula

Hence, The mass of both masses are 0.923 kg and 1.38 kg.

ill do it for 100, also this isnt 80 its 40
