A 00280 kilogram bullet moving horizontally at 400 ms, Ask an Expert

Academics

A 0.0280 kilogram bullet moving horizontally at 400 m/s embeds itself into an initially stationary 0.500 kilogram block.

(a) Find their velocity just after the collision?

(b) The bullet-embedded block slides 8 meter on a horizontal surface with a 0.30 kinetic coefficient of friction. Now determine what is its velocity?

(c) The bullet embedded block now strikes and sticks to a stationary 2 kilogram block. Find how far does this combination travel before stopping?
