7. Determine the kinetic energy of a 12,000 kg car traveling at 5.55 m/s and 19.44 m/s.

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?

Specific heat refers to the amount of heat required to change 1 gram of a substance by degree(s) celsius

5m/swhenhereaches and even steeper slope. if he accelerates at 2 m/s2 for the 5 m slope, how fast is he traveling when he reaches the bottom of the 5 m slope?
