please explain and write neatly
1. Once again we have a skier on an inclined plane. The skier has mass M and starts from rest. Her speed at the bottom of the slope is 12.0 meters/second. The hill is inclined 30 degrees from the horizontal and the length of the slope is 100.0 meters. Use the law of conservation of energy to determine her final speed and write that number down here: What could account for the difference in your...

Section H Name: Date Attend: review Problem: State the question and the situation in 2 sentences. You are to design a "Vibro-Skier Joy Ride"" that has the following characteristics. A 100 kg skier wearing a Velcro vest coasts down a 100 m long 37 slope that has a coefficient of friction between it and the skis of 0.20. At the bottom, the skier enters a level, frictionless surface on which a spring is located. The end of the spring has...

In each problem, make sure that you are clearly defining random variables, stating their distributions, and writing down the formulas that you are using. (That is, write down the pmf, write down mean and variance formulas.) 1. Suppose we have a computer program that attempts to answer a yes or no question for us. The probability that the program will return the correct response 0.6. Suppose we run the program 15 times. Let X be the total number of times...

By now, you may be getting sick of hearing that we may ignore air resistance" in problems. We did that before because we did not have knowledge of forces. But now... Let's see just how powerful air resistance is on Earth. Assuming that we are standing on the surface of Earth, let's find the fractional difference between the maximum heights reached for each case. 1. Simple case first: a ball thrown upwards without air. Find an expression for the maximum...

please explain the answer
1) Up until now we have always ignored air resistance. We should now add it. Let us just think of simple 1-dimensional problem, dropping a ball of mass m from a height H but 2 with air resistance. We can model the air resistance as a force proportional to the velocity, fair = bv. The coefficient bis a constant. (For this problem you can use calculus textbooks or wolfram alpha to do the calculus.) What are...
