Question

A body whose weight is W1=75N is tied to another body whose weight is W2=45N .If the coefficient of kinetic friction between W1 and the inclined plane (25°)AB is 0.15,calculate the coefficient of kinetic between W2 and the inclined plane(15°) BC when the two masses slide down at constant velocity. (answer 0.23)

Answer 1

W1 and W2 are connected by a rope that is passed through apulley.

Answer 2
