A particle can slide along atrack with elevated ends and a flatcentral part,The flat part has length L = 40 cm.The curved portions of the track arefrictionless, but for the flat part thecoefficient of kinetic friction is mk 0.20.The particle is released from rest at point A, which is at heighth = L/2. How far from the left edge of the flat part does the particlefinally stop?
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
A particle can slide along a
track with elevated ends and a flat
central part,
The flat part has length L = 40 cm.
The curved portions of the track are
frictionless, but for the flat part the
coefficient of kinetic friction is mk
0.20.The particle is released from rest at point A, which is at height
h = L/2. How far from the left edge of the flat part does the particle
finally stop?
