Question

As shown in figure,find that at what distance body A will retain a velocity of 3m/s when starts from rest.assume coefficient of friction as 0.2 for block and surface and pulleye are frictionless

Answer 1

for m₁

$m_1g \times sin\theta -T = m_1a$

for m₂

$T-m_2g = m_2 a$

Displacement:

u= 0,

$S = \frac{v^2-u^2}{2a} = \frac{3-0}{2a} = \frac{1.5}{a} m$ from end
