Consider the Atwo
mass=m1 =300g, mass=m2=600g.
When masses m1 and m2 are connected by a string passing over a pulley and when the pulley comes in motion, then mass m2 is stopped in 2 seconds. So, equation of motion is:
T – m1 g = m1 a−−−−(1)
m2 g − T = m2 a−−−−(2)
On solving equations (1) and (2), we get,
a = = = ms-2
In 2 second the velocity acquired by mass m1 is given by,
Applying first equation of motion,
0 = v −×2 or v = ms-1
with acceleration due to gravity i. e.
0 = − − 10 t or t = = sec
