... bob can be resolved into components mgsinθ and mgcosθ. Tension T in the string acts as shown in the fig.. Net force acting on the bob towards pin A = (T - mgcosθ). This force provides the required centripetal force. Hence, (T - mgcosθ) = mv2/(L/2) = 2mv2/L Substituting for mv2 from (2) we get : (T - ...

As such, if an object travels for twice the time, it will cover four times (22) the distance; the total distance traveled after two seconds is four times the total distance traveled after one second. If an object travels for three times the time, then it will cover nine times (32) the distance; the ...

After the collision, however, the baseball moves at a higher velocity away from the bat, and the bat continues in its path, but at a slower velocity. How are the velocities of th ...

... 1. The greatest deceleration (of magnitude a) is provided by the maximum friction force (Eq. 6-1, with FN = mg in this case). Using Newton’s second law, we find a = fs,max /m = sg. Eq. 2-16 then gives the shortest distance to stop: |x| = v2/2a = 36 m. In this calculation, it is important to first ...

... • The action-reaction forces are equal and opposite, but either object may still have a net force on it. Consider driving a nail into wood with a hammer. The force that the nail exerts on the hammer is equal and opposite to the force that the hammer exerts on the nail. But there is a net force actin ...
