$End space straight A space space of space straight a space rod space AB space is space being space pulled space on space the space floor space with space straight a space constant space velocity space space v subscript 0 space as space shown. space Taking space the space length space of the space rod space as space space comma space at space an space instant space when space the space rod space makes space an space angle space 37 to the power of 0 space space with space the space horizontal comma space calculate$

$The space velocity space of space end space straight B$

$\frac{3}{5} v_{0}$
$\frac{4}{5} v_{0}$
$\frac{5}{3} v_{0}$
$\frac{5}{4} v_{0}$

The correct answer is: $4 over 5 v subscript 0$
