Sample Teaching and Assessment Strategies
Extension (continued)
Students may
Solve problems such as the following:
A space station has a radius 175 m. It rotates to simulate
0.65 g. How many rotations per minute does the space
station make?
A person, with a mass of 65.0 kg, on a carnival ride stands
inside a large drum of radius 5.0 m that begins to rotate.
When a safe speed is reached, the floor of the drum falls
away and the rider is left \"stuck\" to the wall. If the coefficient
of friction is 0.54, What is the minimum speed at which the
drum can turn so that the person does not fall?
A roller coaster cart passes the point at the very top on the
inside of a circular loop, which has a radius of 9.00 m. If the
normal force is equal to one half the weight of the cart, what
is the speed of the roller coaster at this point?
