Question

the following figure shows a block of mass m1 resting on a smooth surface. it is connected to a mass m2 by a string passing over a massless and frictionless pulley m2>m1. the acceleration of the hanging mass m2 is: Need to make sure that the answer in the photo is correct d. 30 m's The following figure shows a block of mass m i resting on a smooth surface. It is connected to a mass m2 by a string passing over a massless and frictionless pulley mi>mi. The acceleration of the hanging mass m2 is 4· m, -m m, + m b. m C.m m m2-m m, +m

Explanation / Answer

Solution:

For mass m1:

T = m1 a (Newton's 2nd law)

=> a = T/m1 -----eq 1

For mass m2:

m2 g - T = m2 a

Putting value of T from eq 1 here;

m2 g - m1 a = m2 a

=> m2 g = (m2+m1)a

=> a = m2 g / (m2 + m1)
