Question:
The illustration depicts a situation where an object A is placed on a horizontal surface with friction, and is connected on both sides to objects B and C with a string. The object A is held stationary at point P by a hand. When the hand is released and A starts to move, after seconds, A passes through point Q which is meters away from P The masses of A B and C are kg kg and kg respectively. The coefficient of kinetic friction between A and the horizontal surface is ukNote that the magnitude of gravitational acceleration is g ms
a Using the equation for uniform acceleration, calculate the velocity of A as it passes through point Q
b Create the motion equation for the object and calculate the coefficient of kinetic friction,μk
