Chapter 6, Problem 3RQ
- 3. Your college quadrangle is 85 meters long and 66 meters wide. When you are late for class, you can walk (well, run) at 7 miles per hour. You are at one corner of the quad, and your class is at the directly opposite corner. How much time can you save by cutting across the quad rather than walking around the edge?

4. Jack, an engineering student, is taking in the great view while he was on the ship's deck, but as he is
enjoying the cold wind tickling his face, he noticed that there is an iceberg about to hit the ship, but
instead of reporting it, his curiosity took the best out of him, he hurriedly went to his backpack and took
his notebook and pen out. He wondered how big the iceberg is underneath and how much of it is above
the seawater. By observing, he calculated that the density of the ice is pice = 2013 Ibm/m² and floats in
seawater, and by analyzing the saltiness of the water that hits his face he learned that the density of the
seawater is psw = 1213 kg/m?. (2.25lbm = 1.20kg)
a. What fraction of the iceberg is beneath the surface of the water?
b. What fraction of the iceberg is above the surface of the water?
c. Should Jack ask for Rose's help in the upcoming midterm exam?

Recall the discussion on spacecraft from the chapter opener. The following problems consider a rocket launch from Earth’s surface. The force of gravity on the rocket is given by F(d)=−mk/d2, where m is the mass of the rocket, d is the distance of the rocket from the center of Earth, and k is a constant.
172.
As the rocket travels away from Earth’s surface, there is a distance D where the rocket sheds some of its mass, since it no longer needs the excess fuel storage. We can write this function as F(d)=⎨(−m↓1 k / d^2) if d < D
(−m↓2 k / d^2) if d ≥ D
Is there a D value such that this function is continuous, assuming m1≠m2?

- 2: The lecturer Aous used to drive his car early inorder to arrive and teach his students some engineering subjects in Tikrit University because he lives in Baghdad. The distance between the above two cities (Tikrit and Baghdad) is 160 km, and he always drive in average velocity which is about 75 mile per hour. Determine the time that he should start driving from Baghdad if you know that the first lecture begins at 8:30 a.m Hint: one mile is almost equal to 1.6 kmarrow_forwardAre you as strong as a horse? Purpose: To understand the concept of work and power and to calculate the power generated by yourself or a friend. Materials: A tape measure, stairs, and a stopwatch, cell phone, or wristwatch. Key Physics Concept: Power is the rate of doing work. Power can be calculated by dividing the work done by the time it takes to do the work; in this case we will do work against gravity on a stair case (you may add your power in doing pushups to test your arm power). Can you guess what your peak horsepower is? You may do the stairs one at at time or multiple stairs at a a time; whatever is most safe and efficient for you. Procedure: Observations: Analysis: Conclusions: Application: 1. Will your hp change if you performed the activity for a longer duration (for example, climbed the CN tower staircase)? In what way? Explain. 2. Research the horsepower generated by a car. How does the average person's peak power rating compare to it? How many average people would it…arrow_forwardQuestion 11) Roger gave the following account of a roller-coaster ride: 1 tried a brand-new ride at a science centre. There's a computer screen that tells you how much the car and the people in it weigh and how high and fast you travel. You get into the car and they strap you in. The car weighs 600 kg. At the top, it moves horizontally at a speed of 1 m/s. Then you drop 30 m, make a loop into the air and finish by riding over an 8-m hill. I don't remember our maximum speed or our speed at the top of the loop, but the ride was fantastic!" Answer the following questions without taking the force of friction into consideration. Show your calculations for each question. A v=1 m/s 20 m 8 m a) What is the highest speed Roger could have attained? What is the potential energy of the roller-coaster car when it is at the top of the b) loop? c) What is the kinetic energy of the car as it passes over the top of the 8 m hill? d) What is the total mechanical energy of the system?arrow_forward

To make it more exciting, you decide to string a steamer across the pool so that the swimmers just clear it at their maximum height after leaving the slide. The end of the slide is 0.75 m above the ground and is directed 20° above the horizontal. By watching people use the slide, you know the horizontal distance to place the streamer, so you only need to determine the maximum height. You are also curious how fast the swimmers are going when they enter the pool. In your estimates, you can assume that the swimmer starts at rest at the top of the slide and ignore friction on the slide and air resistance. 2.5 m 0.75 m streamer If the angle of the slide were different (say 15°) would either the maximum height or the speed when entering the water be different? Note: Use conservation of energy to answer these questions.arrow_forwardI need to lift a large engine block but at my age, I can only create 160lbs of force. I will build a lever to assist me.
