Chapter 5: Q5-11Q (page 109)

Can a particle with constant speed be accelerating? What if it has constant velocity? Explain.

Short Answer

Expert verified

Yes, a particle can be accelerated when it is moving with constant speed, whereas there will be no acceleration of particle at constant velocity.

Step by step solution

01

Understanding acceleration

The acceleration of a particle does get affected by the variation in velocity of the particle as well as mass of the particle.

02

Determining the acceleration of a particle at constant speed and constant velocity

When any specific particle is rotating in an orbicular route with constant speed, then it accelerates due to the change in the direction of the particle. On the other hand, at a constant velocity, there will be no acceleration of the particle because there is no variation in the direction as well as the magnitude of the velocity.

A jet pilot takes his aircraft in a vertical loop (Fig. 5鈥�38).

(a) If the jet is moving at a speed of840km/hat the lowest point of the loop, determine the minimum radius of the circle so that the centripetal acceleration at the lowest point does not exceed 6.0 g鈥檚. (b) Calculate the 78-kg pilot鈥檚 effective weight (the force with which the seat pushes up on him) at the bottom of the circle, and (c) at the top of the circle (assume the same speed).

Calculate the force of Earth鈥檚 gravity on a spacecraft 2.00 Earth radii above the Earth鈥檚 surface if its mass is 1850 kg.

(II) Planet A and planet B are in circular orbits around a distant star. Planet A is 7.0 times farther from the star than is planet B. What is the ratio of their speeds \({v_A}/{v_B}\)?

Astronauts who spend long periods in outer space could be adversely affected by weightlessness. One way to simulate gravity is to shape the spaceship-like a cylindrical shell that rotates, with the astronauts walking on the inside surface (Fig. 5鈥�33). Explain how this simulates gravity. Consider (a) how objects fall, (b) the force we feel on our feet, and (c) any other aspects of gravity you can think of.

A penny is placed on a turntable which is spinning clockwise as shown in Fig. 5鈥�37. If the power to the turntable is turned off, which arrow best represents the direction of the acceleration of the penny at point P while the turntable is still spinning but slowing down?
