Answer to Question #39947 in Mechanics | Relativity for Nilam

Question

a)Consider a simple pendulum of mass m mounted inside a railroad car that is accelerating
to the right with constant acceleration a. Analyse this problem in the non inertial frame
of reference to find the angle φ with the vertical direction at which the pendulum will
remain at rest relative to the moving car.
b) On Jupiter a day lasts for 9.9 earth hours and the circumference at the equator is
448600 km. If the measured value of gravitational acceleration at the equator is 24 6. ms ,−2
what is the true gravitational acceleration and the centrifugal acceleration.
