"John" the stair-slider was recently photographed sliding down a staircase. He has a mass of 98.0 kg when sitting on a carpet lubed up on the bottom with a kg of butter. The staircase is 8.2 meters long and makes an angle of 43 degrees with the horizontal. The butter reduces his frictional force to 50.0 N. Stavro begins his slide by running, grabbing his carpet, and launching himself on the stairs with a velocity of 4.89 m/s. Determine:(adsbygoogle = window.adsbygoogle || []).push({});

A) John's acceleration (Draw a Force Diagram of the system to help you)

B) How long is takes John to reach the bottom of the stairs

C) John's velocity at the bottom of the stairs

HELP ME PLEASE! i dont really know where to start
