Roller coaster ride: A roller coaster is being designed that will accommodate 64 riders. The maximum weight the coaster can hold safely is 12,800 pounds. Hence, the maximum mean weight allowed for 64 men on the ride is 200 lbs. According to the National Health Statistics Reports, the weights of adult U.S. men have mean 194 pounds and standard deviation 68 pounds. Assume that U. S. men’s weights are normally distributed. Show which program was used on a TI-84 plus calculator.

a)Find the probability that a randomly chosen man weighs more than 200 lbs.

b) Find the probability that the mean weight of 64 riders is more than 200 lbs.

Roller coaster ride: A roller coaster is being designed that will accommodate 60 riders. The maximum weight the coaster can hold safely is 12,000 pounds. According to the National Health Statistics Reports, the weights of adult U.S. men have mean 191 pounds and standard deviation 65 pounds, and the weights of adult U.S. women have mean 167 pounds and standard deviation 74 pounds. Use the TI-84 Plus calculator. Part 1 of 3 (a) If 60 people are riding the coaster,...

A roller-coaster track is being designed so that the roller-coaster car can safely make it around the circular vertical loop of radius R = 24.5 m on the frictionless track. The loop is immediately after the highest point in the track, which is a height h above the bottom of the loop. What is the minimum value of h for which the roller-coaster car will barely make it around the vertical loop?

Elevator ride: Engineers are designing a large elevator that will accommodate 43 people. The maximum weight the elevator can hold safely is 8643 pounds. According to the National Health Statistics Reports, the weights of adult U.S. men have mean 189 pounds and standard deviation 63 pounds, and the weights of adult U.S. women have mean 170 pounds and standard deviation 72 pounds. Use the TI-84 Plus calculator. (a) If 43 people are on the elevator, and their total weight is...

Mickey Mouse was injured in a work accident on a roller coaster and as a result is entitled to some compensation. The insurance company has offered him the choice of an annual payment each year for the next 20 years, with the first payment being made today, or a lump sum payment now of $1.5 million. If a fair return is 3.5% p.a., how large must the annual payment be to leave him as well off financially as with the...

1) A roller coaster car on the leveled portion of a track is moving at a speed of 35 m/s, heading toward a hump. Based on the principle of conservation of energy, predict what is the velocity of the car on the top of the hump if the lost of energy due to friction and air resistance is negligiable. The highest point of the hump is 14 above the leveled track.

A 300kg roller coaster at an amusement park is at rest on top of a 30m hill (Point A). The car starts to roll down the hill and reaches point B, which is 10m above the ground, and then rolls up the track to point C, which is 20m above the ground. a) Assuming no energy is lost and using energy arguments, how fast is the cart moving at point C? b) What is the total mechanical energy of the...

1. If a roller coaster has a total of 6396 Joules of energy at the top of a hill, then at the bottom of the hill how much total energy will it have. (assume: no brakes, no motor, no air resistance, no external forces) Hint: use conservation of energy! Question 2 If a roller coaster begins at rest at the top of a 20 meter hill, then at the bottom of the hill how fast will it be going? Hint:...

A) a roller coaster it's traveling with a velocity of 20 m/s at the top of an incline. If the incline has a height of 10m, determine the coasters velocity at the middle of the incline. Neglect friction and use 10 m/s^2 for gravity B) a vehicle weighing 15000 nt is traveling at 50 m/s in the i direction. It collides with a wall and stops in 1/10 second. If the collision was inelastic, determine the average force of the...
