Lets see if I can brainwash you, and I am even telling you that I am going to do it.

A man leaves home jogging. He jogs a while and turns left, jogs a little further and turns left, jogs a little further and turns left again. While jogging home he sees two masked men. Who are the masked men?

It is often said "if they can put a nuclear warhead on the missile...". Why is it a problem to put a nuke warhead on a missile that is already known todeliver a regular explosive warhead? Seems it should work whether it is a nuke or regular or confetti and silly putty.

f(x) = 6cot^2(x) / cos^2(x) - tan^2(x) / 7sec^2(x)

Can you solve this and show me the most straightforward way of doing so.

Thanks a lot

Tom the cat is chasing Jerry the mouse across a table surface 1.4 m off the floor. Jerry steps out of the way at the last second, and Tom slides off the edge of the table at a speed of 5.1 m/s. Where will Tom strike the floor, and what velocity components will he have just before he hits? (Use a coordinate system in which up is positive.)

The position vector for a partivle moving on a helix is r(t) =

Find an equation for a tangent line to r(t) =(4pi)/w

What i have done so far is took the derivative of r(t):

r'(t)=<-wsinwt, wcoswt, 2t>

Then I plugged in t = (4pi)/w

and got <0,4pi/w, 8pi/w>

Is this right, am I going in the right direction? Also, how do you get an equation from this?

How do I do this? You guys don't have to do it for me, just get me started.

Thanks!!

You decide to drive around a circular track of radius 50.0 m in your car starting from rest. You accelerate with a constant tangential acceleration of 2.00 m/s2. You are initially at the far west side of the circular track and will travel counter clock-wise.
(a) What is the speed of your car when you have traveled ¼ the circumference of the track?
(b) At that point, what is the centripetal acceleration of your car?
(c) At the same point, what is the total acceleration?
