Rangers at the everglades national park, ride an air-boat, the mass of the air boat plus the rangers is 500 kg. The blades of the boat push on the air with 1000N, while moving the rangers experience an air resistance force of 200N directed opposite to the direction of motion, and the boat a water resistance of 250N. They move in straight line for 20s. Please complete the following tasks:

  1. Draw the free-body diagram showing all forces acting on the air-boat ranger system.

  1. Calculate the net force acting on the boat-ranger system;

  1. Determine the accelerations of the air boat system;

  1. What is the coefficient of friction between the water and the boat?

  1. What is the velocity of the boat at the end of the 20s, if its initial velocity was 20 m/s?

  1. How far did the boat travel in those 20s?

An amusement park ride consists of a cylindrical chamber of radius R that can rotate. The riders stand along the wall and the chamber begins to rotate. Once the chamber is rotating fast enough (at a constant speed), the floor of the ride drops away and the riders remain "stuck" to the wall. The coefficients of friction between the rider and the wall are us and uk. 1. Draw a free body diagram of a rider of mass m after...

The Ocean City water park is considering the purchase of a new log flume ride. The cost to purchase the equipment is $5,000,000, and it will cost an additional $380,000 to have it installed. The equipment has an expected life of six years, and it will be depreciated using a MACRS 7-year class life. Management expects to run about 150 rides per day, with each ride averaging 25 riders. The season will last for 120 days per year. In the...

A pair of bumper cars in an amusement park ride collide elastically as one approaches the other directly from the rear, as seen in part (a) of the figure below. ((a) before collision, (b) after collision) One has a mass of m1 = 462 kg and the other m2 = 546 kg, owing to differences in passenger mass. If the lighter one approaches at v1 = 4.48 m/s and the other is moving at v2 = 3.63 m/s, calculate the...

(a) Have you ever visited an amusement park and taken a ride on a parachute drop ride? These types of rides take the passengers to a great height, and then drop them in free fall. Before they hit the ground, the ride is slowed using a Lenz’s law mechanism thus avoiding certain death. For this discussion, first locate a photo of one of these rides (either one you’ve personally experienced or one you might like to try someday), and in...

In Roosevelt National Forest the rangers took random samples of live aspen trees (Populus tremuloides) and measured the base circumference of each tree. Assume these measurements are normally distributed. (a) The first sample had 30 trees with a mean circumference of 15.71 inches and a sample standard deviation of 4.63 inches. Find a 95% confidence interval for the mean circumference of aspen trees from these data. (b) The next sample had 90 trees with a mean of 15.58 inches and...
