A 75 kg skier was pushed up a slope of 21.0 degrees west with an inititial velocity of 4.0 m/s. After the inital push, it is not pushed further with the up-slope force. The kinetic coefficient of friction between the skis and the snow is 0.14 and the static coefficient is 0.19.  a) What is the acceleration (deceleration) of the skier after the push? b) If his initial velocity was 4.0 m/s, how far up the slope will he move before he stops?

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:
