sideshow strong men‚ each lift 200 kg barbells 2 m off the ground. Atlas lifts his barbells in 1 s and Hercules lifts his in 3 s. a) Which strong man does more work b) Calculate which man is more powerful. 2. A 5000 kg roller coaster train is winched up the first hill‚ which is 80 m high. What is I) the speed of the train over the top of the second hill 70m off the ground and ii) the average breaking force needed to stop the train if it has 100 m to pull into the station?

Roller Coaster We were finally arriving at michigan’s adventure and my brother somehow convinced my whole family to go on a roller coaster‚ and I HATE roller coasters. We finally waltzed into michigan’s adventure. We walked around for a while‚ when finally we found the roller coaster. “Do I have to go on.” I whined. “No.” My dad said. “Yes he does we are going on this as a family‚ but this will be the only one you have to go on.” my mom said. We waited in line for a little while. Suddenly we

History A roller coaster train going down hill represents merely a complex case as a body is descending an inclined plane. Newton’s first two laws relate force and acceleration‚ which are key concepts in roller coaster physics. At amusement parks‚ Newton’s laws can be applied to every ride. These rides range from ’The Swings’ to The ’Hammer’. Newton was also one of the developers of calculus which is essential to analyzing falling bodies constrained on more complex paths than inclined planes. A

Finally once we got to the top‚ it paused. I could feel it lurch forward‚ then leave my insides behind. “How about shivering timbers?” My dad asked “NOOOOO!” I moaned “YES!” My sister screeched “Do we have to.” I complained. I hated wooden roller coasters‚ I always think they would collapse when you ride on it. “Yes.” My dad said‚ you’re the only one on this family that doesn’t want to go. “Mom do you want to go?” I asked “Kind of.” She said between licks of her ice cream cone. “Why do you

The roller coaster is so fast. It is a roller coaster that is never seen before. When you see some roller coaster have some loops and small turns‚ well this is the complete opposite. Consequently‚ You will experience so much during the ride and what is even better is if you chose to ride in a cart that will go twice around for a little bit more so you do not have to wait in line again to ride it another time. The carts are aerodynamic so that he has less air resistance they will have a higher speed

are many things that factor into the making of a roller coaster. Beside the fact of making it fun‚ exhilarating‚ and decently scary you also have to think about the scientific principles. As these will all be defined by Oxford’s dictionary. One of the most common scientific principles is kinetic energy. Kinetic energy is energy that an object possesses by virtue of being in motion. Kinetic energy increases as motion increases during the roller coaster ride. Potential energy is the energy of a body

EXPERIENCE ABOUT ROLLER COASTERS I had a great experience about roller coasters even though I have not climbed one before. Roller coaster is a popular amusement ride developed for amusement parks and modern theme parks. There are two main types of roller coasters which are the steel and wooden roller coaster. Steel coasters have tubular steel tracks‚ and are known for their smooth ride and often convoluted shapes that frequently turn riders’ upside-down via inversions. Wooden coasters have flat steel

Tick‚ Tick‚Tick went the sound of the coaster as I watched it go up the 300 foot drop. Tick Tick Tick. The screams were overtaking the sound of everything. Blood was rushing through my head as I watched the blue cart zoom around the track. My uncle trying to talk me into it. "Come on" he said "No"‚ I replied "It will be fun"‚he said "NO" I said "It is the only ride at Knott’s that we haven’t been on"‚ he said "NOOOO" I said "Were not coming back" he said "So" ‚ I said "It will be fun"‚he said "How

Samantha Robinson Math105 Math and Roller Coasters It’s not something that most people think about when they’re standing in line for an hour waiting for two minutes of thrill‚ but math has a lot to do with building a roller coaster. The engineer needs to know how long and how high the ride needs to be before it can begin to be put together. These measurements have to be precise because the first drop has to give it enough speed to carry it through all the features of the ride. They would
