The posion of an object as a funcon of me is given by x = - ct, where b = 2. 0 m/ and and x and t are in si units. What is the instantaneous velocity of the object when.

Where do magnetic lines of force enter earth?

Aball horizontally thrown from a cliff at 8m/s

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.
