Acar is moving 14.4 m/s. it decelerates at -1.55 m/s^2 for 4.26 s. it then accelerates at 1.83 m/s^2 until it reaches 11.8 m/s. what was the total time?

This is the substance(s) formed in a chemical reaction.

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
