The link above is answers for questions 1-6.
I just need help for questions 10-13 and if you can please answer also 14,15,and 16.
Thank you!
Make sure you show your work for all of the questions Important Info A coaster car has a mass of 230kg and carrie The coaster has a height of 137m at points 1 and 3, 90m at point 4, and 75m at point 5 s 4 people. You can assume that each person has a mass of 60.0kg Point 3 Point 1 This is the start of the coaster ride Point 2 The coaster has just finished the first drop and Top of the world! 4. 5. 6. What would a FBD of the car look like at this point? What force is causing the centripetal acceleration? What is the centripetal acceleration? 1. What is the potential energy of the car has reached ground level. What is the kinetic energy of the car at this point? What is the velocity of the car? at this point? 2. 3. Point 6 Landingl Point 5 Over the Lake! At this point, the car launches itself in projectile motion across a small lake. The car also automatically turns on its purple headlights to shine them at a diffraction grating that is 1cm wide and contains 1000 slits Point 4 Little Loop! 10. What velocity is the car traveling at What are the potential and kinetic energies of the car at this point? 7. when it lands? 11. How wide is the lake? What is the velocity of the car at launch? Draw a diagram of the spectra produced by the diffraction gratin. Make sure to show the distance between the maxima (up to order 3) 8. 9. Connections Point 7 Collision! At this point, the car collides with another, empty, stationary car End of the Ride To make it easier to get the car back to the landing zone before the first hill, the park has installed a maglev system of two parallel 15. There are both inertial and non-inertial frames of reference in this roller coaster Give an example of each and provide proof 12. What is the momentum of each car before the collision? After the collision?conductors that the car travels between. All Assume an elastic collision passengers need to get off 16. A spaceship records that it takes 72s to complete the coaster ride. If the ship is moving at 0.75c, how long does it take to actually complete the ride? 13. What is the velocity for each car after 14. What does the current have tob e in each conductor to create a magnetic field capable of lifting the car? the collision?Explanation / Answer
10.
using conservation of energy between point 5 and landing point
kinetic energy at 5 + Potential energy at 5 = kinetic energy at landing point
0.691 x 105 + 3.454 x 105 = (0.5) m vL2
0.691 x 105 + 3.454 x 105 = (0.5) (230 + 4 x 60) vL2
0.691 x 105 + 3.454 x 105 = (0.5) (470) vL2
vL = 42 m/s
11.
consider the motion along the Y-direction after launch
voy = initial velocity = 0 m/s
a = acceleration = - 9.8 m/s2
Y = vertical displacement = - 75
t = time taken to land
Using the equation
Y = voy t + (0.5) a t2
- 75 = 0 t + (0.5) (- 9.8) t2
t = 3.91 sec
consider the motion along the x-direction
vox = velocity along the x-direction = 294 m/s
X = width of the lake
width of lake is given as
X = vox t
X = 294 x 3.91
X = 1149.54 m
