In the same cable-and-pulley arrangement, the truck moves with constant acceleration $a_{p} = 6$ $m / s^{2}$ from rest. The speed of the block $B$ at the instant $x_{D} = 3$ m is:

Options:

Answer:

Solution:

$v_{D} = 2 \times 6 \times 3 = 6$ m/s; $v_{B} = \frac{1}{3} \times \frac{3}{5} \times 6 = 1.2$ m/s. Option C.
