Chapter 4: Q. 11 (page 104)

11. In FIGURE Q4.11, Yvette and Zack are driving down the freeway side by side with their windows down. Zack wants to toss his physics book out the window and have it land in Yvette's front seat. Ignoring air resistance, should he direct his throw outward and toward the front of the car (throw 1), straight outward (throw 2), or outward and toward the back of the car (throw 3 )? Explain.

Short Answer

Expert verified

The book just needs to move outward straight to Yvette front seat.

Step by step solution

01

Step 1. Given information

Yvette and Zack are driving down the freeway side by side. Since Yvette and Zack both are driving with the same velocity, so there relative velocity is zero. At the time the book is thrown, the component of velocity of book in the direction of car鈥檚 motion is same as the car.

02

Step 2. Explanation

The book will have the same velocity as the car at the moment of the throw. Yvette's car has the same velocity; from the book's perspective both cars are stationary. This means the book just needs to move outward straight to Yvette front seat.

Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 30sto speed up from rest to its top speed of 1rotation every 1.3s. The astronaut is strapped into a seat 6.0mfrom the axis.

a. What is the astronaut鈥檚 tangential acceleration during the first 30s?

b. How many g鈥檚 of acceleration does the astronaut experience when the device is rotating at top speed? Each 9.8m/s2of acceleration is1g.

II As the earth rotates, what is the speed of (a) a physics student in Miami, Florida, at latitude 26掳, and (b) a physics student in Fairbanks, Alaska, at latitude 65掳? Ignore the revolution of the earth around the sun. The radius of the earth is 6400km.

38. II FIGURE EX4.38 shows the angular-velocity-versus-time graph for a particle moving in a circle. How many revolutions does the object make during the first 4 s?

You are asked to consult for the city鈥檚 research hospital, where a group of doctors is investigating the bombardment of cancer tumors with high-energy ions. As figure shows, ions are fired directly toward the center of the tumor at speeds of 5.0脳106m/s. To cover the entire tumor area, the ions are deflected sideways by passing them between two charged metal plates that accelerate the ions perpendicular to the direction of their initial motion. The acceleration region is 5cmlong, and the ends of the acceleration plates are 1.5mfrom the target. What sideways acceleration is required to deflect an ion 2cmto one side?
