Objects and forces: air resistance
As Nogueira stated, the air is made up of more than one particle. If the idea you're using is that a force occurs between two objects, then you'd have to treat each air molecule as an individual objec …

What will be final velocity of three charges $q$, $q$, $2q$?
You're only a half-step away. You listed conservation of energy and linear momentum, both of which are due to there being no external forces on the three-charge system. But with no external forces, yo …

How to solve Kinematics: two objects meeting in the air
You can find the position (as a function of time) for the balloon with simple kinematics:
$y_B=200-\dfrac{1}{2}gt_B^2$
(with $g=+9.8\:m/s^2$).
After five seconds, the archer shoots the arrow upward …

Why dont you take derivative of force in definition of power ? P=F.v
For a force to do work, it must act upon an object as that object moves some distance (with a component along or opposed to the direction of that force). Holding an object stationary, but carrying the …
