Acheerleader waves her "pom-pom" in shm with an amplitude of 18.0cm and a frequency of 0.850hz. find, a) the maximum magnitudes of acceleration and velocity. b) the acceleration and speed when the pom-pom’s coordinate is x = 9.00cm. c) the time required to move from equilibrium position directly to a point 12.0cm away.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

What are some properties of transverse waves?
