A strip of wood of mass `M` and length `l` is placed on a smooth horizontal surface. An insect of mass `m` starts at one end of the strip and walks to the other end in time `t`, moving with a constant speed. The speed of the insect as seen from the ground is

A strip of wood mass M and length l is placed on a smooth horizontal surface. An insect of mass m starts from rest at one end of the strip and walks to the other end in time t , moving with a constant speed.

A strip of wood of length l is placed on a smooth horizontal surface. An insect starts from one end of the strip, walks with constant velocity and reaches the other end in time t_(1) . It then flies off vertically. The strip moves a further distance l in time t_(2) .

A rod of mass 2kg and length 1m is pivoted at one end A and kept on a smooth surface. A particle of mass 500gm strikes the other end B of the rod and sticks to the rod. If particle was moving with the speed of 10m//s , what is the angular speed of the rod after collision ?

A rod of mass 2kg and length 1m is pivoted at one end A and kept on a smooth surface. A particle of mass 500gm strikes the other end B of the rod and sticks to the rod. If particle was moving with the speed of 20m//s , what is the angular speed of the rod after collision ?

A uniform rod AB of mass m and length l is at rest on a smooth horizontal surface. An impulse J is applied to the end B perpendicular to the rod in horizontal direction. Speed of the point A of the rod after giving impulse is:

A uniform rod AB of mass m and length l is at rest on a smooth horizontal surface. An impulse J is applied to the end B , perpendicular to the rod in the horizontal direction. Speed of particlem P at a distance (l)/(6) from the centre towards A of the rod after time t = (pi m l)/(12 J) is.

A wooden plank of mass 20kg is resting on a smooth horizontal floor. A man of mass 60kg starts moving from one end of the plank to the other end. The length of the plank is 10m . Find the displacement of the plank over the floor when the man reaches the other end of the plank.
