The distance from the centre of the table to the block is 15cm.
The rear wheel of a certain car has a diameter of 40cm.State the principle by which a speed governor limits the speed of a vehicle.Iii) The vertical velocity with which the mass strikes the ground. ii) The horizontal distance the mass travels before it strikes the ground.i) The time the mass takes to reach the ground after breaking off.ii) The path of the mass from A until it strikes the ground at a point b.i) The initial direction of the mass at the point the string breaks.The string breaks when the mass is at its lowest position A and at a speed of 30ms -1. The speed of the mass is gradually increased until the string breaks. The diagram below shows a mass m, which is rotated in a vertical circle.Assuming the string breaks when the radius is maximum, calculate the velocity of the mass when the string breaks, given that L 1.25m, and m= 0.1kg.
The maximum tension the string can withstand without breaking is 2N. m is rotated at horizontal plane or radius r as shown. A light inextensible string of length L is fixed at its upper end and support a mass m at the other end.
