Hi i'm working on my homework and im already done but i want to check if i used the correct formula and if i solved it correctly. Can you pls help me understand 1-5 thanks***(THE MASS OF THE COASTER IS 0.002 kg) **( THE VELOCITY in position 1 is 0 m/s)1.) The coaster goes in a 3rd horizontal loop with a radius of 0.04 m. If it spends 0.31 seconds travelling the loop, What would the centripetal force experienced by the marble from the wall of the coaster.2) As the coaster slows down on its last straight piece of track, it goes from a velocity of 4.31 m/s to a velocity of 1.21 m/s over the course of 0.7 s. What is the average force of friction experienced over the straight piece of track?3.)When the marble hits its final destination, it crashes into a wall with a force of -0.70 N in a collision that lasted 0.094 seconds. What was the impulse of the marble?4.) We know conservation of energy, If we assume the track is NOT frictionless would the coasters' total mechanical energy increase or decrease as it goes down? Or would the total mechanical energy stay same at any points/position.5..).A different park has a roller coaster but it starts at a height of 4.5 m and the top of the loop is only 1.9 m above the ground. If it reaches a speed of 3.35 m/s at the top of t loop, what is the momentum of the coaster at that point?
