Solve the each part of given problem:
Problem: If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward the inside of the curve (a real problem on icy mountain roads).
Part A: Calculate the ideal speed to take a 135-m radius curve banked at 18.0°.
Part B: What is the minimum coefficient of friction needed for a frightened driver to take the same curve at 15.0 km/h?
I want help to find the minimum coefficient of friction needed for a frightened driver.
Noether's theorem states that, for every continuous symmetry of a system, there exists a conserved quantity, e.g. energy conservation for time invariance, charge conservation for U(1). Is there any similar statement for discrete symmetries?
Two objects (42.0 and 24.4 kilogram) are connected by a mass less string that passes over a mass less, frictionless pulley. Obtain the acceleration of the objects and the tension in string
