Hey! Just need some help with this. Thanks!

Amusement Park Dynamics 1) This amusement park has a water park section. Inside is a waterslide that travels down on an incline at an angle of 60.0 degrees above the horizontal, and stands 50.0 m tall in the air. The frictional co-efcient between wet berglass and the raft is 0.25. How fast will the rider be going at the bottom of the slide? Must solve using forces, NOT energy. 2) Pick a ride that undergoes centripetal motion. Describe conceptually what the rider feels during the ride. Note: What sections of centripetal motion did we calculate perceived weight in class? Research aspects such as the radius, period, etc. then perform calculations to demonstrate numerically what the rider is feeling during the ride. Make it clear which ride you are using and provide sources for your research. Energy and Momentum 3) a} Two bumper cars travel towards each other as pictured below. The blue one is 635 kg and travels at 5.34 m/s, and the green one is 534 kg and travels at 6.37 m/s. After the collision the green car is traveling at 4.30 m/s. What is the magnitude and direction of the velocity of the blue car? b) Is this collision elastic or inelastic? Describe mathematically and conceptually. 4) For this question, you will be basing your answers on the ride in the following video: Nothing but Net httpswwwyoutube.com/watch?v=1VHJyC3P5Mk To simplify the situation, let's say the rider's energy is absorbed only by the four stretchy elastics at each corner of the net. What is the k value of each cord {assume they are all equal)? If the ride is 30 m tall, and the net extends 1.5 meters at most. You will assume the rider's mass. Fields 5) Old fashioned bumper cars are powered by a charged ceiling and oor. A pole on the bumper car connects these two charged surfaces to give the car current to run. The difference in voltage between the plates is typically around 48 V. Estimate the height difference between the ceiling and floor. When radon in the ground decays it releases an alpha particle. Assuming the ceiling is negatively charged, the alpha particle could be accelerated towards the ceiling. It is not good for people to be hit with fast moving alpha particles. Mathematically show if this is something we need to be concerned about. Note: Think about the height of a person and how fast the particie could be moving when it hits them. is it moving at a siow drift, or an appreciabie speed of fight iike nuclear radiation? 6) At night the amusement park puts on a rework display and hands out \"fireworks glasses\" a) What type of slit is this, single, double, or multi? And now do you know? b) Make assumptions about the spacing of bright spots, wavelength, and distance from the glasses to your eye. Depending on your answer to part a, determine the slit width or distance between slits. c) Why did the white light disperse into colours? Give details of why we see the colours in the location we do. Modern Physics 7) The amusement park is trying to incorporate more ecofriendly practices. As a result, they are installing solar panels to help power the park. If the panel is made of silicon metal with a work function of 4.7 eV and some green light from a re work lands on it, will the panel generate any current? If yes, state with what velocity the electrons leave the plate, if no, how much more energy would be needed to eject an electron
