Chapter 7: Q. 3 (page 176)

How does a rocket take off? What is the upward force on it?Your explanation should include an interaction diagram and free-body diagrams of the rocket and of the parcel of gas being exhausted.

Short Answer

Expert verified

Exhausted gases and a high upward force propel the rocket forward.

Step by step solution

01

Free body diagram

02

Explanation

The rocket pushes the exhaust gases down.

The heated gases are pushing up against it.

According to Newton's third law, the two forces constitute a pair.

Because the force of the combustion products on the rocket is heavier of gravitational, the rockets accelerates upward.

A 40cmdiameter, 50cmtall, 15kghollow cylinder is placed on top of a 40cm-diameter, 30cm-tall, 100kgcylinder of solid aluminum, then the two are sent sliding across frictionless ice. The static and kinetic coefficients of friction between the cylinders are 0.45and 0.25, respectively. Air resistance cannot be neglected. What is the maximum speed the cylinders can have without the top cylinder sliding off?

Your forehead can withstand a force of about 6.0kNbefore fracturing, while your cheekbone can withstand only about 1.3kN. Suppose a 140gbaseball traveling at 30m/sstrikes your head and stops in 1.5ms

a. What is the magnitude of the force that stops the baseball?

b. What force does the baseball exert on your head? Explain.

c. Are you in danger of a fracture if the ball hits you in the forehead? On the cheek?

Block Ain FIGUREEX7.5is sliding down the incline. The rope is massless, and the massless pulley turns on frictionless bearings, but the surface is not frictionless. The rope and the pulley are among the interacting objects, but you’ll have to decide if they’re part of the system.

A 2.0kg rope hangs from the ceiling. What is the tension at the midpoint of the rope?

The century-old ascensores in Valparaiso, Chile, are picturesque cable cars built on stilts to keep the passenger compartments level as they go up and down the steep hillsides. As FIGURE P7.43shows, one car ascends as the other descends. The cars use a two-cable arrangement to compensate for friction; one cable passing around a large pulley connects the cars, the second is pulled by a small motor. Suppose the mass of both cars (with passengers) is 1500kg, the coefficient of rolling friction is 0.020, and the cars move at constant speed. What is the tension in (a) the connecting cable and (b) the cable to the motor?
