A spray-painter nozzle normally produces droplets of paint in a cone shaped beam of width 30 ̊. What do
you think would be the effect on the beam if each droplet were given a large positive charge as it left the
nozzle? Give your reasons.

(a) What is the angular momentum of a particle of mass m that moves in a circle of radius r at the speed v? (b) An earth satellite follows an elliptical orbit in which its maximum altitude above the earth’s surface is 2000 km and its minimum altitude is 400 km. Use the result of (a) to find the ratio between the maximum and minimum speeds of the satellite.

The box having mass of m is being pulled by a motor. Initial velocity of the box is vy, Motor pulles the box by force F= 500s+550, where s is the distance the box is pulled (meters), and force is in newtons. Define the velocity and acceleration of the box as a function of distance 's'. If the motor has efficiency of e = 0.65, power input required to be supplied by the motor as a function of distance,

Positions of 2 blocks are placed on the plane and released as depicted in the figure. The coefficients of kinetic friction between the blocks and the ground are uA=0.2 and us=0.4, respectively. Find the force emerging in the link which connects blocks A and B together. Mass of the link is neglected. Block A and block B weighs 20kg and 4 kg.
