Chapter 4: Q. 32 (page 107)

I To withstand "g-forces" of up to10g 's, caused by suddenly BI0 pulling out of a steep dive, fighter jet pilots train on a "human centrifuge." 10g's is an acceleration of 98m/s2. If the length of the centrifuge arm is 12m, at what speed is the rider moving when she experiences 10 g's?

Short Answer

Expert verified

The speed of the rider is34.29m/s.

Step by step solution

01

 Step 1. Given information

The centrifugal acceleration of the fighter jet pilot is 10 g that is 98m/s2, the length of the centrifuge arm is 12m.

02

Step 2. Explanation

The centrifugal acceleration of the pilot of the fighter jet is,

-ac=v2r

Here,ac is the centrifugal acceleration of the pilot, vis the linear speed of the pilot, and ris the length of the centrifuge arm.

98m/s2=v2(12m)

v=98m/s2脳(12m)=34.29m/s

Thus, the linear speed of the rider is 34.29m/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?

Ships A and B leave port together. For the next two hours, ship A travels at 20mphin a direction 30掳west of north while ship B travels 20掳east of north at 25mph.

a. What is the distance between the two ships two hours after they depart?

b. What is the speed of ship A as seen by ship B?

A 35 g steel ball is held by a ceiling-mounted electromagnet 3.5 m above the floor. A compressed-air cannon sits on the floor, 4.0 m to one side of the point directly under the ball. When a button is pressed, the ball drops and, simultaneously, the cannon fires a 25 g plastic ball. The two balls collide 1.0 m above the floor. What was the launch speed of the plastic ball?

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?

8. A particle's trajectory is described by x=12t3鈭�2t2mand y=12t2鈭�2tm, where t is in s.
