To the ceiling of a carriage moving uniformly and rectilinearly relative to the Earth at a speed, the modulus of which is 20 km / h. a ball is suspended on a thread.
a) Does the state of this ball differ from the state of the same ball moving uniformly and rectilinearly at a speed whose modulus is 60 km / h?
b) Will the position of the ball change if the car starts moving at an accelerated rate?
a) No, both balls are at rest, b) Yes, the ball will deviate from the equilibrium position.
