I am currently pursuing a MS in Physics at Rutgers University, and I love helping fellow students find their passion in school. I have been a tutor for 5 years helping students across various subjects but mainly focusing on STEM related studies. My goal as a tutor is to present information in a fun, quirky, and digestible way so students leave each video having understood the information and come back eager to learn more!
Use Galileo's velocity addition rule. Let $\mathcal{S}$ be an inertial reference system.(a) Suppose that $\overline{\mathcal{S}}$ moves with constant velocity relative to $\mathcal{S}$. Show that $\overline{\mathcal{S}}$ is also an inertial reference system. [Hint: use the definition in footnote 1.(b) Conversely, show that if $\overline{\mathcal{S}}$ is an inertial system, then it moves with respect to $\mathcal{S}$ at constant velocity.
As the outlaws escape in their getaway car, which goes $\frac{3}{4} c,$ the police officer fires a bullet from the pursuit car, which only goes $\frac{1}{2} c$ (Fig. 12.3 ). The muzzle velocity of the bullet (relative to the gun) is $\frac{1}{3} c .$ Does the bullet reach its target (a) according to Galileo, (b) according to Einstein?
Synchronized clocks are stationed at regular intervals, a million km apart, along a straight line. When the clock next to you reads 12 noon:(a) What time do you see on the 90 th clock down the line?(b) What time do you observe on that clock?
Every 2 years, more or less, The New York Times publishes an article in which some astronomer claims to have found an object traveling faster than the speed of light. Many of these reports result from a failure to distinguish what is seen from what is observed-that is, from a failure to account for light travel time. Here's an example: A star is traveling with speed $v$ at an angle $\theta$ to the line of sight (Fig. 12.6 ). What is its apparent speed across the sky?
The coordinates of event $A$ are $\left(x_{A}, 0,0\right), t_{A},$ and the coordinates of event $B$ are $\left(x_{B}, 0,0\right), t_{B} .$ Assuming the interval between them is space like, find the velocity of the system in which they are simultaneous.
40 lbF = 60 lbDetermine the magnitude and direction of the resultant force. Show your work:R = 80.3 lb, θ = 106.2°R = 80.3 lb, θ = 73.8°R = 72.1 lb, θ = 63.6°R = 72.1 lb, θ = 116.4°
A mass with mass 3 is attached to a spring with spring constant 75.083333333333 and a dashpot giving a damping 30. The mass is set in motion with initial position 0 and initial velocity 4. (All values are given in consistent units.) Find the position function x(t):x(t) =
The motion is (select the correct description)
A. overdampedB. critically dampedC. underdamped
If the system is underdamped, rewrite your answer in the formx(t) = cos( t - )If your answer is not underdamped, enter "N" in each of these answer blanks.
