Lab Report 5

For Vi prime, I divided my Ws, in my case 0.0458 m by Ti prime, in my case 0.3957 s, for an answer of .1157 m/s. Of course, MapleTA isn't accepting my answer. Any suggestions on what am doing wrong/how I can get MapleTA to accept my answer?

It is asking what happens in elastic and inelastic collisions both before (ρ) and after the collision (ρ). From your observations, or rather ideal observations, what happens in such collisions?

does anyone understand Q24, how do you get deltaP'? THANKS.

For Question 24 let's figure out two things. Since we are finding ρ, what is the formula for it, i.e. how do we find it?

To find Deltaρ we use Equation 7 from E&U. What does that equation look like? Can you put that equation into terms which express ρ? Meaning what values would you use in the equation that you used for ρ?

We'll take it step by step of need be, get back to me, let me know if you got it or are still confused.

Is the formula for 24 for delta p:

deltap=p*sqrt((deltam/m)^2+(deltav/v)^2) ?

Also, for q24 for deltap' am i using the total for both masses as m?

does anyone know q 36 total KE and total KE'??

That's it, that's the formula!
Just remember to multiply ρ after the sqrt(...).

As for which mass to use, think of it this way, the momentum is the object that is moving. Since the big glider is moving, only that has momentum and it is pre-collision, notated by ρ. In the inelastic collision, bith the object stick together, correct? so the momentum will be both masses added since it essentially becomes one big glider.

So yes you are using the total.

how do we calculate deltavi(prime)/vi(prime) in #9?

#29?

#33 please
