Find the velocity of point G.

Text Solution

Verified by Experts

In string ABCD from first format of constrain `V_D = 10 m//s uarr`
Now `V_D = (V_H + V_E)/2`
`V_H = 10 m//s darr` if upward direction is taken to be positive
`+ 10 = (-10 + V_E)/(2) implies V_E = 30 m//s uarr`
Now `(V_F + V_G)/(2) = V_(E) implies 30 = (-10 + V_G)/(2)`
`60 + 10 = V_(G)`
`V_(G) = 70 m//s uarr`.
