A girl decides to become a cowgirl and is practising her lasso moves. She swings her lasso over her head at a radius of 1m with a centripetal acceleration of 16 m/s^2. What is the tangential speed, frequency and period of her lasso?

I've been trying to figure out how to do this but to no avail. Any step by step help would be greatly appreciated and rewarded points.

Using the laws of motion why would you have a better chance of escaping an elephant if you ran in a zig-zag path rather than a straight line?

My physics is only up to A-Level, so I'm probably wrongly mixing Newtonian physics with photons...

Can someone explain a simple derivation?

For kinetic energy:
E = 1/2 x m v^2

So I wondered why mv [momentum] does not equal 2E/c (kinetic energy equation) when it's applied to photons.

we have 200, four-hundred pound men, sitting inside a bus traveling at 200 miles per hour, (the men are seat-belted of course for safety reasons)
if one these men falls out of the bus at the 100 mile mark, thus increasing the bus speed to 225 miles per hour, how long will it take this bus to travel 400 miles???

A uniform bar has two small balls glued to its ends. The bar is 2.00 m long and with mass 4.00 kg, while the balls each have mass 0.500 kg and can be treated as point masses.

1. Find the moment of inertia of this combination about an axis perpendicular to the bar through its center.

2. Find the moment of inertia of this combination about an axis perpendicular to the bar through one of the balls.

3. Find the moment of inertia of this combination about an axis parallel to the bar through both balls.

4. Find the moment of inertia of this combination about an axis parallel to the bar and 0.500 m from it.

Here is the question:


If you had twoforces,one with a magnitude of 25N and the other with a magnitude of a 100N,what would be the maxiumum net force these forces could exert on an object?

Could you help explain to me how to figure this out?
