In a velocity-time graph what is represented by the slope, or steepness of the graph line.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

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?

Place me with this question is my last question
