Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

A 100-kg box is towed to move horizontally from rest by a constant force P=200 N. The kinetic friction is μk =0.1. The angle of the force P is θ=30° with respect to the horizontal direction.

A manufacturer is carrying out a vehicle performance analysis and subjects to a road test. The vehicle is driven along a horizontal road at velocity V. The vehicle weighs 1.79tons and for each wheel the radius is 0.31m and the MMofI is 5.53kgm2. The coefficient of friction between the wheels and the road surface is 0.43. Given g=9.81m/s2 and the length between the center of rear and front wheel is 3.9m. The height of center of gravity is 0.95m while its horizontal distance to the center of rear wheel is 1.72m. If only the front wheels are locked and there is no rear wheel braking, calculate the deceleration (m/s) of the vehicle. Submit your answer as a positive value.
A carnival ride has people stand inside a vertical cylinder with their backs to the wall. The cylinder starts spinning and the riders find that they are “stuck” to the wall and don’t slide down, even if the floor is removed. The ride has a radius of r. The person has a mass of m and is moving with a constant speed of v. The coefficient of static friction between the person and the wall is μs , and kinetic friction μk. The person is only touching the wall, not touching the floor. What is the magnitude of the acceleration of the person? In what direction does it point? The speed is constant. Why is the acceleration not zero? Briefly explain. No equations!
