L3 ROTATIONAL MOTION
... Use the above information to explain why tightrope walkers carry a long bar? A tightrope walker will often carry a long bar ‘for balance’. If the tightrope walker falls, it will be because he has rotated too far about his foot (the CoR). Increasing his reluctance to rotate would be a great advantage ...

Centripetal force and Centrifugal force
... Centripetal force is commonly seen when driving a car. If the car approaches a curve, the road must be engineered to compensate for the curve. The road must provide an additional force so that the car can round the curve and not continue on a straight path. Centripetal Force Now we will consider the ...

12.3 Velocity and Acceleration
... As an object moves along a curve in the plane, the coordinates x and y of its center of mass are each functions of time t. Rather than using the letters f and g to represent these two functions, it is convenient to write x = x(t) and y = y(t). So, the position vector r(t) takes the form r(t) = x(t)i ...

... A 0.5 kg ball is dropped to the floor from a height of 2 m. If it bounces back to a height of 1.8 m, what is the magnitude of its change in momentum? Some energy is lost in the bounce. Just before it hits the ground, its velocity is: (use conservation of ME) mgh=1/2mv2 so v=(2gh)=(2*9.8*2)= 6.26 m ...
