facebook onwz. My first entire week was called WOW week, week of welcome at cal poly. We were in small groups with 2 leaders and we went on tours around campus, town went to the beach, some hot springs and did some group games. A ton of fun:cool:

When the moving sidewalk at the airport is broken, as it often seems to be, it takes you 50 s to walk from your gate to baggage claim. When it is working and you stand on the moving sidewalk the entire way, without walking, it takes 75 s to travel the same distance. How long will it take if...

nothing, that is the only info givin.

A 22-cm-diameter bowling ball has a terminal speed of 85m/s. What is its mass. I get F=M(9.8). But then i don't know where to go from there or what to do with the 22 cm diameter :confused:

this is a calc problem, but I thought it fits better here than in the math section since its homework. Here it goes: the great pyramid of cheops is 410 feet tall and 755 feet square at the base. find the volume of the pyramid using calculus. Part two: The stone used in constructing...

bump, anyone

lol, yea I have the equations, but out of laziness I just used the ones in this thread :redface: , thanks for the help though :smile:

ok, i think my error came from using the following equation: x_f=x_i+v_i+\frac{1}{2}at^2 shouldnt there be t after the v_i

ok, I got 2169.05 m/s for the velocity as it passes the judges, can someone else do the problem and tell me what you get.

ok, so the two equations for the first interval is V_f1=9aand X_f1=40.5a Now I am not sure if i plugged them in right, but I got 20.45 as A_1 Put 990 as X_f, 40.5a as X_1, 9a for V_1, then -5 as a_2 and 3 for deltaT_2

We have to solve this problem, but also do a write-up on it similar to how the textbook gives example problems. Here is the problem: Your school science club has devised a special event for homecoming. You've attached a rocket to the rear of a small car. The rocket provides a constant...

thank you guys:cool:

Jill has just gotten out of her car in the grocery store parking lot. The parking lot is on a hill and is tilted 3 degrees. Fifty meters downhill from Jill, a little old lady let's go of a fully loaded shopping cart. The cart, with frictionless wheels, starts to roll straight downhill. Jill...

A rocket is launched straight up with constant acceleration. Four seconds after liftoff, a bolt falls off the side of the rocket. The bolt hits the ground 6.70 s later. Find the rockets acceleration. I don't understand how to set up this problem, I've never done something like this ...
