You need to use the rigid body acceleration equations to relate the accelerations of O and the center of mass of the bar, G, through the angular acceleration of the bar. Also, you need to relate the ...

The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time. \(\text{Gradient} = \frac{{change\,in\,velocity ...

We now use the following equation to calculate the acceleration: \(a=\frac{(v-u)}{t}\) Watch this video to see the correct procedure for carrying out this investigation.

The chances of intelligent life emerging in our Universe -- and in any hypothetical ones beyond it -- can be estimated by a new theoretical model which has echoes of the famous Drake Equation. This ...
