Question

As ahown in the figure find that at what distance body A will attain a velocity of 3 m/s.when starts from the rest.Asaume coefficient of friction is 0.2for blocks and surface and pulleys are weightless and 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
