An object has velocity `vecv_1` w.r.t. ground. An observer moving with constant velocity `vecv_0` w.r.t. ground measures the velocity of the object as `vecv_2`. The magnitudes of three velocities are related by

A

`v_0gev_1+v_2`

B

`v_1lev_2+v_0`

C

`v_2gev_1+v_0`

D

All of the above

Text Solution

Verified by Experts

The correct Answer is:
B
b. `vecv_2 = vecv_1 - vecv_0, vecv_2 + vecv_0 = vecv_1`
From the law of triangle, we can draw the
velocity vector diagram.

From triangle property, sum of two sides gethird
side. So `v_1le v_0 + v_2` .

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.
