When traveling a highway in the mountains, you may see elevation signs that read "914 m (3000 ft)". Critics of the metric system claimt hat such numbers show the metric system is more complicated. How would you alter such signs to be more consistent with...

Again Chapter one Stuff... Discuss how the notion of symmetry could be used to estimate the number of marbles in a one-liter jar. I'm lost I'm thinkthing somewer along the lines of counting them up nice and simple but I have no idea

I posted questions down below about chapter 1 aparently they were missed.

can you please explain this to me... Were given this eqaution x = At^2 + B were A = 2.10 m/s^2 B = 2.80 m ok and this is an example problem and it's wlking us through it find the instantaneous velocity at t=t2=5.00s equlas the slope of the tangent to the...

Hello I was trying to find the proof of the formula x = x0 + v0t +.5at^2 were the zeros are subscripts My text book dosen't explain it that well. ok well it involves the formula for average velocity aver velocity = 2^-1(v0 + v) were the zero is a subscrip...

hi I need help on this proof ok I'm tyring to prove that v^2 = v^20 + 2a(x -x0) where the zeros are subscripts ok the first step my book says is start out with x = x0 + average velocity (t) then plug in average velocity x = x0 + (2^-1(v + v0))t ok and the...

Hello given that I person 65 kg takes 4.5 s to climb a flight of stairs that is 5.5 m my question is well I was asked to solve for the work and W=fd and in this case f is equal to the normal force correct? Just take the opposite of mg??????? Also I'm aske...

I'm trying to derive the formula v^2 = v0^2 + 2a(x-x0) were zeros are subscripts my book tells me to derive it this way use the definition of average velocity to derive a formula for x use the formula for average velocity when constant acceleration is ass...

wow ok thanks I thought it was more complicated thanks!

I FIGUERED IT OUT THANKS

Thank You
