A ship is sailing towards the north at a speed of 1.25 m/s. The current is taking it towards the east at the rate of 1 m/s and a sailor is climbing a vertical pole on the ship at the rate of 0.5 m/s. Find the velocity of the sailor in space.

A square loop of side 12 cm with its sides parallel to X and Y axes is moved with a velocity of 8cms^(-1) in the possitive x-direction in an environment containing a magnetic field in the positive z- direction. The field is neither uniform in space nor constant in time. It has a gradient of 10^(-3)Tcm^(-1) along the negative x-direction (that is it increases by 10^(-3)T as one moves in the negative x-direction), and it is decreasing in time at the rate of 10^(-3)Ts^(-1) . Determine the direction and magnitude of the induced current in the loop of its resistance is 4.50mOmega .

A dumb bell consists of two identicasl small balls offmss 1/2 kg each connected to the ends of a 50 cm long light rod. The dumb bell is rotating about a fixed axis through the centre of the rod and perpendicular to it t an angular speed of 10 rad/s. An impulsive force of average magnitude 5.0 N acts on one of the masses in the direction of its velocity for 0.10s. Find the new angular velocity of the system.
