Chapter 1: Q. 22 (page 29)

Draw a pictorial representation for the following problem. Do

not solve the problem. What acceleration does a rocket need to reach a speed of 200 m/s at a height of 1.0 km?

Short Answer

Expert verified

A pictorial representation of a rocket that reach a speed of 200m/sat a height of1kmis given here.

Step by step solution

01

Introduction

The rocket is moving with a constant acceleration at reaches at a height of1kmwith a final speed of200m/s.A diagram showing the motion of the rocket in two different situation is shown here.

02

Pictorial representation

The rocket is moving with a situation where y1=0,v1=0,t1=0and reaches at a height with a condition ofy2=1km,v2=200m/s. The value of acceleration should be found.

The particle model for the motion of the rocket should be as follows:

The speed-time graph represents acceleration of the object for the given situation can be plotted as:

Now, the pictorial representation for the given situation is,

FIGURE EX1.18 shows the motion diagram of a drag racer. The camera took one frame every 2 s.

a. Measure the x-value of the racer at each dot. List your data in a table similar to Table 1.1, showing each position and the time at which it occurred.

b. Make a position-versus-time graph for the drag racer. Because you have data only at certain instants, your graph should consist of dots that are not connected.
