Friction Problem

Two masses M1 and M2 are connected by a light rod and the system is slipping down a rough incline of angle theta with the horizontal. The frictional coefficiant at both the contacts is u fhnd the accelaration of the system and the force by the rod on one of the blocks. Friction problem from … Continue reading Friction Problem

Homework from Projectile Motion

A projectile is projected at an angle theta with horizontal with speed u . If air resistance is taken in account , the angle with vertical at the time of hitting the ground will be a)more than (90 + theta) b)less than (90 – theta) c)(90 + theta...
