Straight Line Motion Revisited Homework Answersl

New! A new student section has been written called Calculus from 30,000 feet. Borrowed from Steven Strogatz's book Infinite Powers, this addendum is meant to be used after the AP exam and gives students a greater insight into how the Infinity Guideline breaks down comples probems into simper ones and then reassembles them. No homework or problems - just an attempy to see the Calculus forest from the trees.

Straight Line Motion Revisited Homework Answersl


To find the observable consequences of this curvature we need to take another step. When spacetime is flat freely moving objects obey Newton's first law i.e. they move in a straight line at constant speed. When spacetime is curved freely moving objects obey a different equation called the geodesic equation:

But all this is a bit abstract, and I suspect you're after a more intuitive feel for how does spacetime curvature cause straight lines not to be straight? Well the most obvious definition of a straight line is the path of a light ray, because we all learn in school that light travels in straight lines. And the obvious demonstration of this is the bending of light rays by the Sun.

If we shine a light ray so that it just grazes the Sun's surface then that light doesn't travel in a straight line. We can calculate the deflection using the geodesic equation and the values of the Cristoffel symbols, and we find the light ray is bent by about $1.75$ arcseconds. But this is a tiny, tiny amount. $1.75$ arcseconds is about the angle subtended by a baseball at a distance of $9$ kilometers - you couldn't even see a baseball $9$ km away!

11. Consider two cylinders that start down identical inclines from rest except that one is frictionless. Thus one cylinder rolls without slipping, while the other slides frictionlessly without rolling. They both travel a short distance at the bottom and then start up another incline. (a) Show that they both reach the same height on the other incline, and that this height is equal to their original height. (b) Find the ratio of the time the rolling cylinder takes to reach the height on the second incline to the time the sliding cylinder takes to reach the height on the second incline. (c) Explain why the time for the rolling motion is greater than that for the sliding motion.

An object at rest (not moving) will remain at rest unless acted on by an unbalanced force. Also, an object in motion will continue to move at a constant speed in a straight line unless acted on by an unbalanced force.

In 2-d projectile motion without air resistance the equation relating the velocity ##\vec v_\!f## at time ##t_\!f## and the initial velocity ##\vec v_0## is $$\vec v_\!f=\vec v_0+\vec gt_\!f.$$The three vectors participating in the equation form a closed triangle the sides of which are ##OA = v_0##, ##OF = v_\!f## and a third vertical side ##AF = g t_\!f## (see figure 1). Triangle OAF in the figure corresponds to a projectile that is at positive vertical displacement ##\Delta y## at time ##t_\!f## after reaching maximum height. I call this the velocity triangle; its geometric construction from three given lengths is outlined in Appendix I. Triangle OAB is another velocity triangle corresponding to the projectile returning to launch level and is drawn for later reference.

Beyond being a curiosity, the position triangle can serve as a useful tool for solving problems that cannot be addressed by a velocity triangle construction. Consider the problem in which a projectile is fired up a plane inclined at angle ##\alpha## relative to the horizontal. The projection angle is ##\beta## relative to the incline and we are seeking the landing distance ##d## up the incline. The traditional strategy is to find the trajectory parabola by eliminating ##t_\!f## from the horizontal and vertical position equations, find the horizontal distance ##x_\!f## at which the parabola intersects the straight line ##y = x \tan\alpha##, find the final height ##y_\!f## and finally use the Pythagorean theorem to find the required distance ##d##. This two-page solution can be reduced to two lines using the position triangle.
