Question

Block A with a mass 10kg , rest on a 35 ° incline the coefficient of static friction is 0.40 .an attached string is parallel to the incline and passes over a massless frictionless pulley at the top the largest mass m of block B attached to the dangling end for which A begins to slide down the incline is

Answer 1

Answer:

we know,

$f = (mew)w \\ > f = 0.40 \times fs \cos\alpha \\ > 0.4 \times s \cos35 = 1 \\ > s = \frac{1 }{0.4 \times \cos35 } = \frac{1}{0.33} = 0.0303$
