Question: As a roller coaster car crosses the top of a 48.01-m-diameter loop-the-loop, its apparent weight is the same as its true weight. What is the car's speed at the top? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
As a result of the friction between their surfaces, after a while, both disks spin at the similar angular speed. Determine the work done by the frictional torque.
In a needle biopsy, a narrow strip of tissue is extracted from a patient using a hollow needle. Rather than being pushed by hand, to ensure a clean cut the needle can be fired into the patient's body by a spring. Find the maximum speed of the needl..
