	<title>Comments on: A block weighing 50kg is sliding down a slope of gradient 15 degrees. It&#8217;s initial velocity, at the point A is 4m/s. Calculate it&#8217;s final velocity when it reaches the bottom of the slope, at the point B, 10m away from A. The coefficient of friction between the block and the slope is 0.3.

Any help on how to answer this question would be greatly appreciated. Thanks :)</title>
