Consider the given system shown in fig.
At certain instant velocity of lift (w.r.t. ground). Velocity of A(relative to lift) are shown. Velocity of lift is constant.
Choose correct option

A

Velocity of A relative to ground is `6m//s` upward.

B

Velocity of B relative to ground is `2 m//s` upward

C

Velocity of B relative to ground is `4 m//s` downward

D

Velocity of A relative to ground is `4 m//s` upward.

Text Solution

Verified by Experts

The correct Answer is:
B

w.r.t lift block B will be move down with `4m//s`
So velocity of B w.r.t. ground
`vec(v)_(B//L)+vec(v)_(L)" "implies+6+(-4)implies2 m//epsilon`

We know that when a boat travels in water, its net velocity w.r.t. ground is the vector sum of two velocities. First is the velocity of boat itself in river and other is the velocity of water w.r.t. ground. Mathematically: vecv_(boat) = vecv_(boat,water) + vecv_(water) . Now given that velocity of water w.r.t. ground in a river is u. Width of the river is d. A boat starting from rest aims perpendicular to the river with an acceleration of a = 5t, where t is time. The boat starts from point (1,0) of the coordinate system as shown in figure. Assume SI units.
