First, draw a diagram as it makes the problem easier to understand. Show the turntable and mass. Label the distance between the mass and the centre of the turntable r as it is a radius. write down all var...

Energy = force x distance and Energy = 0.5 x mass x velocity squared

Hence, force = (0.5 x mass x velocity squared) / distance --- (equation 1) This applies for both situation A and B, and given th...

A moment about a point is the product of a force applied and the distance perpendicular to the line of action of that force. So M = F*d

For this we need to use a SUVAT equation. S=displacement U=initial velocity V=final velocity A=acceleration T=time In the question we are give U=0m/s since the ball is at rest to start with Since the ball...

Young's modulus = stress/strain. Stress = F/A Strain= e/l. Measure the length of a wire between 2 points, placing a marker at each. Also measure the diameter to calculate the cross sectional area of the w...
