Determine its velocity just before it crashed

Reference no: EM13708495

Problem: A truck initially descending at a constant velocity of 4.25 m/s down a hill inclined at 30° to the horizontal plane suddenly experienced brake failure and accelerated by gravity until it went into a ditch 60 m downhill.

Part I: Determine its velocity just before it crashed.

Please, try to give explanation for above problem. Thanks.
