A1.2 kg block sliding on a horizontal frictionless surface is attached to a horizontal spring with k =480 n/m. let x be the displacement of the block from the position at which the spring is upstretched. at t = 0 the block passes through x = 0 with a speed of 5.2 m/s in the positive xdirection. what are the (a) frequency and (b) amplitude of the block’s motion? (c) write an expression for x as a function of time

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?
