Question #39947

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.
