(I) the mass is released and slides 3.0m down the slope; calculate the acceleration of the mass as it travels down.

(II) calculate the speed of the lock as it hits the bottom of the slope

(III) what is the speed of this block as it hits the bottom of the slope if the experiment was repeated with a 4kg block?
