Classical Mechanics
Two inclined planes intersect each other so as to form an equilateral triangle when viewed in vertical plane cross section. A string runs over a smooth pulley fastened at the triangle apex to masses m1 dan m2, one on each inclined plane. Use the method of virtual work to find the coefficient of static friction if the masses are on the verge of slipping in one direction (Assume ยต the same on both planes ; neglect mass and stretching of string)

List of five key physical requirements that would be important for a solar-powered plane, briefly explaining your reasoning for each item.
Classical Mechanics
A 9 mm bullet ifs fired from from a 9 mm pistol at 300 meters per second, horizontally to the Earth's surface from 4 feet above the Earth's surface.. At the same time, a 9mm bullet was dropped from 4 feet above the ground. Will the 2 bullets hit the Earth's surface at the same time?

Hello sir
My question is this: If two cars which are exactly the samme hit each other in a head to head position, one of them has a velocity of 50km/h and the other one has a velocity of 5km/h, What would be the impact of the crash for each car ? and what would be the velocity of each car after the crash ?
Thank you so much

generally we define MASS as the quantity of matter in a body.. What does the term" quantity of matter" means?
Classical Mechanics
a 60m ladder weighing 100N rests against a wall at a point 48 degree north above the ground. the center of gravity of the ladder is 1/3 the way up. a 160N man climbs halfway up the ladder assuming that the wall is friction less. find the reaction on the wall and the frictional force.

2 trains each of length 120 m are running on parallel tracks. One train overtakes the other in 24 seconds and one crossed the other in 12 seconds . What are the velocities of the train?

Classical Mechanics
If a body goes with uniform velocity then suddenly it changes its direction then acceleration is produced in the body and then body again goes with uniform velocity .how will we find acceleration in the body when it changes its direction for some time ??
Classical Mechanics
If a body changes direction for a short time and then again travels with constant velocity then how we will calculate acceleration as we know that when direction changes acceleration is produced ??
