Electrical resistors have a design resistance. The resistors are produced by a machine with an output that is Normally distributed with mean 501 ohms and standard deviation 3 ohms. Resistance below 498 ohms and above 508 ohms are rejected. Find: ( The proportion that will be rejected: (4marks) (1) How much the standard deviation would need to be reduced (leaving the mean at 501 ohms) so that the proportion of rejected below 498 ohms would be halved. (8marks)

The ball has a mass \(m\) and is attached to the cord of length \(I\). The cord is tied at the top to a swivel and the ball is given a velocity \(\mathbf{v}_{0}\). Show that the angle \(\theta\) which the cord makes with the vertical as the ball travels around the circular path must satisfy the equation tan \(\theta \sin \theta=v_{0}^{2} / g l\). Neglect air resistance and the size of the ball.

7. A bungee jumper with mass m 50 kg leaps fron a bridge. The jumper is attached to the bridge by an elastic cord with axial stiffness k = 0.10 kN m-1. The cord unravels to its ful unstretched length 3.0s after the jumper has left the bridge. Starting from when the jumper leaves the bridge, determine the earliest time at which the elastic cord reaches its maximum extension. Neglect air resistance.[15
