To the captain of a ship A travelling with velocity `vecv_(A)=(3hati-4hatj)km..h`, a second ship B appears to have a velocity `(5hati+12hatj) km//h`. What is the true velocity of the ship B?

In a reference frame a man A is moving with velocity (3hati-4hatj)ms^(-1) and another man B is moving with velocity (hati+hatj)ms^(-1) relative to A. Find the actual velocity of B.

A boat is moving with a velocity (3hati-4hatj) with respect to ground. The water in river is flowing with a velocity (-3hati-4hatj) with respect to ground. What is the relative velocity of boat with respect to river?

In a 3D coordinate system a plane mirror is placed parallel to XY plane and above the mirror a point object is moving at velocity vecv_(0)=5hati-3hatj-1lhatkm//s If mirror is also moving parallel to it self at velocity vecv_(m)=2hati+hatj-3hatk, find the velocity of image produced in mirror, [5hati-3hatj+5hatkm//s]

A boat is moving with a velocity (3hati +hatj) with respect to ground. The water in the river is moving with a velocity -3hati - 4hatj with respect to ground. What is the relative velocity of boat with respect to river ?

A boat stems in a river with velocity 2hati + hatj with respecitve to the ground. The river water flows with a velocity -3hati - 4hatj with respect to the ground. What is the relative velocity of boat w.r.t river water ?

A boat stems in a river with velocity 2hati + hatj with respecitve to the ground. The river water flows with a velocity -3hati - 4hatj with respect to the ground. What is the relative velocity of boat w.r.t river water ?
