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...

A roller coaster is created with a hill of height 125 m and a loop with radius 45m. To make the crowds swoon, a new cart is brought in: a hollow sphere of mass 250kg and radius 2m, capable of carrying four passenger of total mass, 400kg. The hollow sphere is capable of carrying passengers around the roller coaster separately. Friction although present is mostly negligible. 1.1 What is the initial energy of the system if the cart is released...
