a- A 3.0 kg crate is dragged 6 m across the horizontal floor with a 20 N force making 30° angles above the horizontal. If the coefficient of kinetic friction is 0.2. . Find the work done by all forces acting on the crate. • If the crate started from rest, calculate its speed at 5 m from its original position. A sound wave in the air can be described by: Y(2,t) = 4.0 x 10-9 cos(3.66x – 1256t) What is the maximum displacement, wavelength, frequency, and speed of the sound wave?
