A rocket sled accelerates to 41 m/s. When the rocket engine stops, the sled skids along its rails. If the coefficient of
friction is 0.5 and its mass is 1000 kg, how fast is the sled moving after 2.2 s?
A 10 kg box is being pushed across a rough surface with a constant speed of 2 m/s. The person pushing the box slips and stops pushing. The box continues to slide across the surface before coming to rest. If the coefficient of friction between the crate and the surface is 0.1, how far does the box travel before coming to rest?
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?
