Chapter 9: Q. 6 (page 227)

A particle moving to the left is slowed by a force pushing to the right. Is the work done on the particle positive or negative? Or is there not enough information to tell? Explain.

Short Answer

Expert verified

Work done on the particle is negative

Step by step solution

01

Given Information

A particle moving to the left is slowed down by a force acting to the right.

02

Explanation

We know the work done is positive when direction of force and displacement are same.


In this case the force is acting to right and the movement of the particle is to the left. Which in opposite direction to each other so the work done by the force on the particle is negative.

A 2.0kg particle moving along the x-axis experiences the force shown in FIGURE. The particle’s velocity is 4.0m/s at x=0m. What is its velocity at x=2m and x=4m?

The gravitational attraction between two objects with masses m1 and m2, separated by distance x, is F=Gm1m2/x2 , where G is the gravitational constant.

a. How much work is done by gravity when the separation changes from x1 to x2? Assume x2<x1.

b. If one mass is much greater than the other, the larger mass stays essentially at rest while the smaller mass moves toward it. Suppose a 1.5×1013kg comet is passing the orbit of Mars, heading straight for the sun at a speed of 3.5×104m/s What will its speed be when it crosses the orbit of Mercury? Astronomical data are given in the tables at the back of the book, and G=6.67×10-11Nm2/kg2. .

A 35-cm-long vertical spring has one end fixed on the floor. Placing a 2.2 kg physics textbook on the spring compresses it to a length of 29 cm. What is the spring constant?

You need to raise a heavy block by pulling it with a massless rope. You can either (a) pull the block straight up height h, or (b) pull it up a long, frictionless plane inclined at a 15o angle until its height has increased by h. Assume you will move the block at constant speed either way. Will you do more work in case a or case b? Or is the work the same in both cases? Explain.
