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