    Magnetic sphere moving through iron dust; find velocity & other things

    Homework Statement A small magnetic sphere of initial mass Mo and initial radius Ro is moving through a space filled with iron dust. During its motion, 5% of displaced dust is deposited uniformly onto the surface of sphere. Given the density of dust to be ρ, find: 1. relation rate of increase...

    Pebble dropped on rotating wheel, starts to slide after rotation

    Homework Statement A wheel of radius R=50cm rolls along the ground with velocity V=2m/s. A pebble released on top of the wheel so that it is instantaneously at rest on the wheel. The co-efficient of friction between wheel and pebble is μ=1. The pebble starts to slide down when it has rotated...

    How Does the Velocity of a Suspended Mass Change with Height?

    Homework Statement A body of mass 5kg is suspended at the lower end of a mass-less string, which passing through a mass-less pulley and is being pulled down at the other end by a force of 500N. The force of the pull reduces at a rate of 30N per meter, through which the body is raised. What is...
