Can a body be in equilibrium when only one force acts on it? Explain.

Short Answer

Expert verified

As the net force on the object is not zero, the body is not in equilibrium.

Step by step solution

01

Equilibrium

For an object to be in equilibrium, the net force on the object must be zero. The object in equilibrium can be stationary or moving at a constant velocity.

For example, an airplane moving at a constant velocity can be in equilibrium, as the lift produced by wings is balanced out with weight and thrust is balanced out with drag force.

02

Given Case

In the given case, only one force acts on the body, imparting an acceleration. Hence, this body is not in equilibrium.

Consider a spacecraft in an elliptical orbit around the earth. At the low point, or perigee, of its orbit, it is 400 km above the earth鈥檚 surface; at the high point, or apogee, it is 4000 km above the earth鈥檚 surface. (a) What is the period of the spacecraft鈥檚 orbit? (b) Using conservation of angular momentum, find the ratio of the spacecraft鈥檚 speed at perigee to its speed at apogee. (c) Using conservation of energy, find the speed at perigee and the speed at apogee. (d) It is necessary to have the spacecraft escape from the earth completely. If the spacecraft鈥檚 rockets are fired at perigee, by how much would the speed have to be increased to achieve this? What if the rockets were fired at apogee? Which point in the orbit is more efficient to use?.

Question: Starting with the definition 1 in. = 2.54 cm, find the number of (a) kilometers in 1.00 mile and (b) feet in 1.00 km.

A car travels in the +x-direction on a straight and level road. For the first 4.00 s of its motion, the average velocity of the car is Vav-x=6.25m/s. How far does the car travel in 4.00 s?

You decide to visit Santa Claus at the north pole to put in a good word about your splendid behavior throughout the year. While there, you notice that the elf Sneezy, when hanging from a rope, produces a tension of 395.0鈥�Nin the rope. If Sneezy hangs from a similar rope while delivering presents at the earth鈥檚 equator, what will the tension in it be? (Recall that the earth is rotating about an axis through its north and south poles.) Consult Appendix F and start with a free-body diagram of Sneezy at the equator.

How many nanoseconds does it take light to travel 1.00 ft in vacuum? (This result is a useful quantity to remember.)?
