A 0.16 kg block oscillates back and forth along a straight line on a frictionless horizontal surface. Its displacement from the origin is given by the following equation.x = (8 cm)cos[(5 rad/s)t + p/2 rad)]
(a) What is the oscillation frequency?Hz(b) What is the maximum speed acquired by the block?cm/sAt what value of x does this occur?cm(c) What is the magnitude of the maximum acceleration of the block?cm/s2At what values of x does this occur? (Type your answers in any order. If there is only one answer, type 'none' in the second box.)cmcm(d) What force, applied to the block, results in the given oscillation?( N/cm)x
The equation of a transverse wave traveling along a very long string is y = 5.0 sin (0.055 ?x + 6.0 ?t), where x and y are expressed in centimeters and t is in seconds. Determine the amplitude of propagation of the wave.
