Is event sequencing relative? Lately I have been thinking of a thought experiment involving a proof for relative event sequencing. Absolute sequencing would involve event "a" triggering event "b" and ANY observer perceiving event "a" happening first and event "b" happening second. Relative...

Alright, thanks for your help!

Oh... I am not versed in calculus at all :l. could you explain the process?

Homework Statement At time t = 0 a drag racer starts from rest at the origin and moves along a straight line with velocity given by v = 5t^2, where v is in m/s and t in s. The expression for the displacement of the car from t = 0 to time t is (a) 5t^3 (b) 5t^3/3 (c) 10t (d) 15t^2 (e) 5t/2...

Let me clarify the Static Friction and Kinetic Friction... Static Friction is the friction the object needs to overcome to start moving. Kinetic Friction is the friction the system or object encounters while moving.

Nevermind... I see what I did wrong.. KE= 1/2 mv^2 DUHHHH

This is a very vague question though. Look, there are 2 or 3 types of friction which you might encounter in a basic physics class. The first type its called "Static Friction" and the second is called "Kinetic Friction." In Static Friction the object is not yet moving and therefore it generates...

Homework Statement An Alpha Particle is emitted with a kinetic energy of 2.34 MeV during a radioactive decay process. The maximum speed of the alpha particle is? Homework Equations KE=mv2 1 ev = 1.6x10-19j The Attempt at a Solution \sqrt{(2.34x10^6)(1.6x10^-19)/4(1.6x10^-27)} Unfortunately...

(Note: Planck's Reduced constant = 1.055x10^-34 and 1 ev = 1.6x10^-19 J) The question gives you that information

Homework Statement The Y Meson has a rest mass of 9.6 GeV/c2 and a measured width of (Delta)E= 51keV. What is its approximate lifetime (delta)t? Homework Equations E=MC2 And.. who knows? The Attempt at a Solution We came to the conclusion that 9.6 GeV/c2 was related to E=MC2.. and we...

I found the gravitational potential energy at the center of the meter stick (.5 meters) PEg= (.2)(9.81).5) = .981 Then I made .981 equal to the Kinetic Energy of an object in rotation .981= (1/2)Iw^2 Where I is Moment of Inertia and w is angular velocity I=MR^2 1.962=(.2)(.5^2)w^2 w= 6.2641...

I would put A and C for that problem since you can interpret an Efield in terms of vectors. The direction of the Efield would be that in which a Positive Charge would flow towards... Let's look at it now. A) To the right of Point C Lets Analyze it: If you put a positive charge, it will be...

Could you show me step by step how to do it

This is how you solve it. There are two building, the height difference between both of them is 2.5 meters. Y (displacement in the vertical axis) = 2.5 We are in Earth, so the acceleration due to gravity is 9.81 m/s^2 a (acceleration) = 9.81 The Cat is resting and then begins...

Homework Statement This was a TMSCA (Texas Math and Science Competition) from the physics section. A thin meter stick of mass 200g is positioned vertically on a frictionless table. It is released, slips, and falls. Find the speed of its center of mass just before it hits the table.Homework...
