The motion of the outer frame B is given by $x_B = b sin \omega$t. For what range of the driving frequency $\omega$ is the amplitude of the motion of the mass m relative to the frame less than 2b?

Why is identifying the frame of reference important in describing motion?

In the Earth reference frame, box 1 is approaching box 2, which is initially at rest on a low-friction floor, with velocity v. Box 1 has five times the inertia of box 2. They collide elastically. Calculate the velocities before and after collision in (a) the Earth reference frame and (b) the zero-momentum reference frame.

Explain what is meant by a frame shift mutation.

Identify each of the following groups of words as a sentence or a sentence fragment. On the line provided, write S if the group of words is a sentence or F if it is a fragment.

In a CBS News/ New York Times nationwide poll done in 2009, the proportion of respondents who thought that it should be illegal to use a handheld cellular telephone while driving a car was .80 (80%). The poll's sample size was 829.(a). Find the value of the standard error of the sample proportion. (b). Find a 95% confidence interval estimate of the population proportion who think that it should be illegal to use a cellular telephone while driving. (c). Find a 98% confidence interval estimate of the population proportion who think that it should be illegal to use a cellular telephone while driving. (d). Which of the intervals calculated in parts (b) and (c) is wider-the interval with 95% confidence or the interval with 98% confidence?

A child pedals a tricycle, giving the driving wheel an angular speed of $0.373 \mathrm{rev} / \mathrm{s}$. If the radius of the wheel is $0.260 \mathrm{~m}$, what is the child's linear speed?

The United States Postal Service will mail an envelope that is no greater than $2 x+1.5$ inches long and no greater than $x+1$ inches high. The total area of an envelope with the maximum dimensions is approximately $69 \mathrm{in}^2$. Calculate the approximate maximum dimensions of an envelope that can be mailed through the USPS.

After driving from Tuсson to Phoenix the number of miles on your car's odometer went from 312 to 428. What was the change in the number of miles on your car's odometer?

What is the axial load in member $B D$ of the frame?

Gabor stands on a cart that moves with a constant velocity. In his frame of reference, he tosses a ball vertically up and down. Lutaaq stands on the ground nearby. She also tosses a ball vertically up and down with respect to her frame of reference. (a) Explain what the motion of Gabor's ball looks like from Lutaaq's frame of reference. (b) Explain what the motion of Lutaaq's ball looks like from Gabor's frame of reference.

Using the vocabulary list for this lesson, supply the correct word to complete each sentence.

His _____ lifestyle caught up with him when he was arrested for driving while intoxicated.

When two identical objects traveling at the same speed collide head-on, an observer standing in the Earth reference frame sees both objects changing direction. Do observers in every inertial reference frame that is moving relative to the Earth reference frame also see both objects changing direction?
