Web8 apr. 2024 · Then, The time after which both bodies meet = distance traveled / relative speed. = dkm/ (x – y) km/hr. Now, we know that the relative speed is the speed of one … WebThink about Newton's first law: An object in motion will stay in motion at a constant speed in a straight line unless acted on upon by an outside force. An object that is moving has inertia that causes it to want to stay in motion in a straight line. But if an object is moving in a circle, the velocity is no longer in a straight line.

WebThe relative motion of the body is observed from a particular frame of reference and varies with respect to the choice of frame of reference. When both frames of reference, S and S’, are moving relatively at a constant velocity, the accelerations of the bodies observed from both frames of reference are equal.
