the brakes applied to a car produces an acceleration of 6m/s^2 in the opposite direction to the motion. if the car takes 2s to stop after the application of brakes. calculate the distance it travels during this time .

Afisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. it takes a time of 2.70 s for the boat to travel from its highest point to its lowest, a total distance of 0.700 m. the fisherman sees that the wave crests are spaced a horizontal distance of 6.50 m apart. a. how fast are the waves traveling? b. what is the amplitude a of each wave?
