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’s 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’s tangential acceleration during the first 30s?

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

FIGURE Q4.13

A computer hard disk 8.0cmin diameter is initially at rest. A small dot is painted on the edge of the disk. The disk accelerates at 600rad/s2for 12s, then coasts at a steady angular velocity for another 12s.

a. What is the speed of the dot at t=1.0s?

b. Through how many revolutions has the disk turned?

A spaceship maneuvering near Planet Zeta is located atr^=(600i^−400j^+200k^)×103km , relative to the planet, and traveling at v→=9500ı^m/s. It turns on its thruster engine and accelerates with a→=(40ı^−20k^)m/s2for 35min. What is the spaceship's position when the engine shuts off? Give your answer as a position vector measured in km.

In one contest at the county fair, seen in FIGURE CP4.81, a spring-loaded plunger launches a ball at a speed of 3.0m/sfrom one corner of a smooth, flat board that is tilted up at a 20°angle. To win, you must make the ball hit a small target at the adjacent corner, 2.50maway. At what angle θshould you tilt the ball launcher?
