One end of a uniform meter stick is placed against a vertical wall . the other end is held by a lightweight cord that makes an angle with the stick. the coefficient of static friction between the end of the meter stick and the wall is 0.40.

a. what is the maximum value the angle can have if the stick is to remain in equilibrium?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
