In the above question,if both are in opposite direction. Then the velocity of the pulse w.r.t. to groun will be:

A circular loop of rope of length L rotates with uniform angular velocity omega about an axis through its centre on a horizontal smooth platform. Velocity of pulse (with resppect to rope ) produce due to slight radiul displacement is given by (omegaL)/2(pi) ,if both are in opposite direction. Then the velocity of the pulse w.r.t. to groun will be:

A circular loop of rope of length L rotates with uniform angular velocity omega about an axis through its centre on a horizontal smooth platform. Velocity of pulse (with resppect to rope ) produce due to slight radiul displacement is given by (omegaL)/(2pi) , if the motion of the pulse and rotation of the loop, both are in same direction then the velocity of the pulse w.r.t. to ground will be:

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. Find time taken by him to across the river.
