On a long horizontally moving belt (Fig.), a child runs to and fro with a speed 9 km h^(-1) (with respect to the belt) between his father and mother located 50 m apart on the moving belt. The belt moves with a speed of 4 km h^(-1) . For an observer on a stationary platform outside, what is the (a) speed of the child running in the direction of motion of the belt ?. (b) speed of the child running opposite to the direction of motion of the belt ? (c ) time taken by the child in (a) and (b) ? Which of the answers alter if motion is viewed by one of the parents ?

A projectile is fired at a speed of 100 m/s at an angel of 37^0 above the horizontal. At the highest point, the projectile breaks into two parts of mass ratio 1:3 the smaller coming to rest. Find the distance from the launching point to the where the heavier piece lands.

A shell is fired from a cannon with a velocity V at an angle theta with the horizontal direction. A the highest point i its path, it explodes into two pieces of equal masses. One of the pieces retraces its path to the cannon. The speed of the other priece immediately after the explocison is

A point charge is moving along a straight line with a constant velocity v. Consider a small area A perpendicular to the direction of motion of the charge . Calculate the displacement current through the area when its distance from the charge is x. The value of x is not large so that the electric field at any instant is essentially given by Coulomb's law.
