1. A ball is dropped from rest from the top of a building of height h. At the same instant, a second ball is projected vertically upward from ground level, such that it has zero speed when it reaches the top of the building.
a. When do the two balls pass each other? Answer it in terms of h.
b. Which ball has greater speed when they are passing?
c. What is the height of the two balls when they are passing?
A battery having an emf of 11.10 V delivers 102 mA when connected to a 61.0 load. Find out the internal resistance of the battery.
If the two balls started rolling at the same time at a point 1.2 m behind the edge of the table, will they reach the floor at the same time? define.
A light plane is headed due south with a velocity of 157 km/h relative to still air. After 1.00 hour, the pilot notices that they have covered only 121 km and their direction is not south but southeast (45.0^circ).
Assume that the blocks accelerate as shown with an acceleration of magnitude a= 0.550 m/s^2 and that the coefficient of kinetic friction between block 2 and the plane is μ= 0.400. Find out the mass of block 2, m2, when θ= 30.0.

A moving particle encounters an external electric field that decreases its kinetic energy from 8650 eV to 7540 eV as the particle, Determine the charge of the particle. Include the algebraic sign (+ or ?)
A plot of pressure as a function of volume is known as a pV diagram. pV diagrams are often used in analyzing thermodynamic processes. Consider an ideal gas that starts in state O, as indicated in the diagram. Your task is to explain how the gas proce..
