A skier with mass of 55 kg (including winter clothes and ski equipment), slides straight down a smooth slope (not unlike a flat inclined plane) that makes an angle of 50° with the horizontal. What is the skiers weight in ewtons? Waht is the normal force excerted by the snow on the skier? What is the force of friction between the skies and the snow? What is the net foce acting on the skier? What is the skiers net acceleration down the slope?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
