Question

Velocity of block $B$ in pulley block system as shown in figure is $\frac{60}{n} m / s$ . What is the value of $n$

Open in App

Solution

If v be the velocity of B along A, then by constraint relation , $10 cos 53^{0} = v cos 37^{0}$
this gives $v = \frac{10 \times 3 / 5}{4 / 5} = \frac{30}{4}$
compairing with given value $\frac{60}{n}$ , we get value of $n = 8$
