After collecting so much Halloween candy, you want to find a secret place to eat it all without being bothered. You see a small hiding place on top of a neighbors shed. Luckily, the neighbor has a ramp that leads up to the roof of the shed. You pull your bag of candy with a mass of 6.2 kg up the frictionless ramp which is at an angle of 29 degrees above the horizontal. The bag has an acceleration of 1.81 m/s2 parallel to, and UP the ramp while you are pulling -What is the Normal Force exerted on bag of candy by the ramp? - What force do you need to pull with in order to give the bag an acceleration of 1.81 m/s2?

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
